Foreword
ISO (the International Organization lor Standardizatioη) is a worldwide lederation 01 national standards bodies
(ISO member bodies). The work 01 preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject lor which a technical committee has been established has
the right to be represented on that com 们nittee. International organizations , governmental and non-governmental ,
in liaison with ISO , also take part in the work. ISO collaborates closely with the International Electrotechnical
Cornmission (IEC) on all matters 01 electrotechnical standardization
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives , Part 2
The main task 01 technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies lor voting. Publication as an
International Standard requires approval by at least 75 % 01 the member bodies casting a vote
Attention is drawn to the possibility that some 01 the elements 01 this document may be the subject 01 patent rights
ISO shall not 扫 e held responsible lor identi巾 ing any or all such patent rights

Introduction
It is necessary that users of this International Standard be aware that further or differing requirernents can be
needed for individual applications. This International Standard is not intended to inhibit a vendor from offering , or
the purchaser from accepting , alternative equipment or engineering solutions for the individual application. This
can be particularly appropriate where there is innovative or developing technology. Where an alternative is 0柯e 陪 d ，
it is necessary that the vendor identify any varialions from Ihis Inlernational Standard and provide delails
A bullel (e) al Ihe beginning of a clause or subclause indicates Ihat either a decision is required or the pυrchaser
is required 10 provide further information. 1I is necessary Ihat Ihis information should be indicaled on data sheets

6.1
General
6.1.1
The equipment (i ncluding auxiliaries) covered by this International Standard shall be designed and
constructed lor a minimum service Ii le 0120 years (excluding normal-wear pa时s as identilied in Ta担le 20) and at
least 3 years 01 uninterrupted operation. Shutting down the equipment to perform vendor-specilied maintenance
or inspection does not meet the continuous uninterrupted operation requiremen t. It is recognized that these
requirements are design criteria and that service or duty severity , mis-operation or improper maintenance can
result in a machine lailing to meet these criteria
•
6.1.2 The purchaser shall specify the operating conditions, the Ii quid prope时 ies ， site conditions and utility
conditions , including all data shown on the process data sheet (Annex N). The purchaser shall specify whether
the pump is intended lor use as an HPRT and whether Annex C shall apply
6.1.3 The equipment shall be capable 01 operation at the normal and rated operating points and any other
anticipated operating conditions specilied by the purchaser
6.1.4 Pumps shall be capable 01 at least a 5 % head increase at rated conditions by replacement 01 the
impeller(s) with one(s) of larger diameter or di背'erent hydraulic design , variable而speed capability or use of a blank
stage
This requirement is intended to prevent a change in selection caused by refinement of hydraulic requirements
after the pump has 扫 een purchased. It is not intended to accommodate luture expandability. If there is a fu!ure
operating requirement , it should be specified separately and considered in selection
6.1.5 Pumps shall be capable of
con!inuous speed shall be
ope阻 ting
at least up to the maximum continuous speed. The maximum
a)
equal to the speed corresponding to the synchronous speed at maximum supply frequency lor electrical
motors;
b)
at least 105 % 01 rated speed lor variable-speed pumps , and any lixed-speed pump sparing or
pump 山 hose driver is capable 01 exceeding rated speed
6.1.6
Variable 町 speed
spared 扫 ya
pumps shall be designed lor excursions to trip speed without damage
6.1.7 The conditions in the seal chamber required to maintain a stable Iilm at the seal laces , including
temperature, pressure and flow, as well as provisions lor assuring the adequacy 01 the design lor sealing against
atmospheric pressure when pumps are idle in vacuum service , shall be agreed upon 扫 y the pump vendor and the
seal manulacturer, approved by the purcl飞 aser ， and noted on the data sheet
Provision lor sealing against atmospheric pressure in vacuum service is especially important when handling
liquids near their vapour pressure (such as liquelied petroleum gases). During operation , the seal chamber
pressure shall be at least a gauge pressure 01 35 kPa (0 ,35 bar; 5 psi); see ISO 21049
6.1.8 The vendor shall specify on the data sheets the NPSH3 based on water [at a temperature 01 less than
55 oc (130 OF)] at the ra!ed flow and ra!ed speed. A reduction or correction factor for Ii quids other than water
(such as hydrocarbons) shall not be applied
The purchaser should consider an appropriate NPSH mar臼in in addition to the NPSH3 speci扫ed. An NPSH
margin is the NPSH tha! exists in excess 01 the pump's NPSH3. It is usually desirable to have an operating NPSH
margin that is sufficien! a! all 节 ows (from minimum continuous stable flow to maximum expected operating 由 ow) to
protect the pump from damage caused by flow recirculation , separation and cavi!a!ion. The vendor should be
consul!ed about recommended NPSH margins lor the specilic pump type and intended service

the allowable nozzle loads 01 Table 5 applied through each nozzle;
b)
withstand the hydrostatic test (see 8.3.2)
NOTE
The twice 响。zz!e斗。 ad requîrement is a pressure-casing des 唱 n criterion. Al1 0wab恒 nozzle loads for piping
desîgners are the values given in Table 5, which , În addition to pressure casing design , include other factors that affect

the minimum ultimate tensile strength or 0 ,67 times the minimum yield strength for that material , whichever is

shall be multiplied by the appropriate casting lactor , as shown in Table 4. The manulacturer , in his proposal , shall
state the source 01 the material prope 时ies from those listed in Table H.2 (I. e. ISO , ASTM , UNS , EN , JIS) , as well
as the casting lactors applied. National material standards other than those listed in Table H.2 , may be used with

NOTE 1
In genera l, the crìterìa ìn 6.3.3 result in deflectìon (strain) being the determining consideration in the design of
pump casings with respect to p陪 ssure 阳 tention and nozzle loads. Ultimate tensile or yield strength is seldom the limiting
factor
NOTE 2
For bolting , the allowable tensìle stress is used to determine the total bolting area based on hydrostatic load or
gasket preload. 1t is recognized that to provide the initial10ad required to obtain a reliable bolted joint , lt is necessary that the
bo!ting be tightened to produce a tensile stress higher than the design tensile stress. Values in the range of 0 ,7 to 0 ,9 times

Enclosed (closed) impelle阻 are less sensitive to axial position and , therefore , prefe阻 ble for long shaft assemblies
where axial displacement due to thermal expansion/con甘action or to thrust can be substantia l. Semi-open
impellers can 0忏er a higher efficiency , due to the elimination of disc friction from one shroud. The running
clearances for semi-open impellers in vertical pumps can be adjusted from the coupling or top of the motor , thus
possibly restoring efficiency and pump output without disassembly of pump pa叫s. The open impeller is typically of
an axlal四flow propeller type designed for large capacities at low heads; the open impeller is also used for volute
sump pumps with a separate discharge

tighten by liquid drag on the impeller dυring normal rotation , and a positive mechanical Jocking method (Ior
example a staked and corrosion-resistant set-screw or a tongue-type washer) is required. Cap screws shall have

When establishing internal running clearances between wear rings and other mov',ng pa吐 s ， consideration
shall be given to pumping temperatures , suction conditions , the liquid properties , the thermal expansion and
galling characteristics of the materials , and pump efficiency. Clearances shall be sufficient to assure
dependa坦 ility 01 operation and freedom from seizure under all specified operating conditions
b)
For cast iron , bronze , hardened martensitic stainless steel and materials wi\h similarly low galling tendencies ,
the minimum clearances given in Table 6 shall be used. For materials with higher galling tendencies and for
all mater国 Is operating at temperatures above 260"C (500 "F) , 125 ~m (0 ,005 in) shall be added to these
diametral clearances
c)
For non-metallic wear-ring materials with very low or no galling \endencies (see Table H.3) , clearances less
than those given in Table 6 may be proposed by the vendor. Factors such as distortion and thern旧 1 gradients
shall be considered , to ensure clearances are sufficient to provide dependa训 ity of opera\ion and freedom

Torsional analysis
6.9 , 2, 1
There are three general types of torsional analyses that are normally performed on pumps
a)
undamped natural frequency analysis: determination of the unit's torsional natural frequencies and
associated mode shapes and generation of a Campbell diagram to determine potential resonance points;
b)
steady-state damped response analysis: evaluation of the resonance points uncovered in the undamped
analysis via a forced response analysis that utilizes representative values for excitation magnitudes and
damping; the results are cyclic torques and stresses in all shaft elements in the model , which can then þe
used to evaluate the structural a时equacy of the machine;
c)
transient torsional analysis: similar to a steady同 state damped response analysis , except that it is done for the
transient condition and its results are' cyclic torques and stresses as functions of time; by far , the most
common application for this analysis type is the sta仲up of a synchronous motor
A flow chart for the torsional analysis is shown in Figure 29

Experience 01 some manulacturers is that vertical pumps , particularly those with long shafts , have relatively large
inertias in the driver and pump stages and are susceptible to very small torsional excitations
The analysis shall be lor the train as a whole unless the train includes a device that has weak dynamic coupling ,
lor example a hydraulic coupling or torque converte r. In all cases , the vendor having unit responsibility shall be

An appropriate cumulative fatigue algorithm shall be used to develop a value for the safe number of
starts. The purchaser and vendor shall mutually agree as to the safe number of starts
NOTE
Values used depend on the analytical model used and the vendor's exper陆 nce. Values of 1 000 to 1 500 starts
are common. ANS lJAPl Std 541 requires 5 000 starts , This is a reasonable assumption for a motor since it does not add
slgn 吁 icant cost to the des唱 n. The driven equipment , however, wou!d be over-designed to meet th们s requirement
EXAMPLE
A 20-year life with 才 start per week equals 1 040 sta 同S. Equipment of this type normally starts once
years rather than once per week. lt is necessa 叩， therefore , to specîfy a reasonable number of starts

Vibration
6.9.3.1
Centrifugal pump vibration varies with flow , usually being a minimum in the vicinity of best efficiency
point flowrate and increasing as flow is increased or decreased. The change in vibration as flow is varied 什om
best efficiency point flowrate depends upon the pump's energy density , its speci币 c speed and its suction-speci白c
speed. In general , the change in vibration increases with increasing energy density , higher specific speed and
higher suction-specific speed
With these general characteristics , a centrifugal pump's operating flow range can be divided into two regions , one
termed the best efficiency or preferred operating regi。矶 over which the pump exhibits low vibration , the other
termed the allowable operating region , with the limits , both high and low , defined as those flowrates at which the
pump's vibration reaches a higher but still "acceptable" leve l. Figure 30 illustrates the concep t. Factors other than
vibration , for example , temperature rise with decreasing flow or NPSH3 with increasing 古ow， can dictate a
narrower allowable operating region. See also 6.1.12
The allowable operating reg 由 n shall be stated in the proposa l. If the allowable operating region is limited by a
factor other than vibration , that factor shall also be stated in the proposal
6.9.3.2
During the performance test , overall vibration measurements over a range of 5 Hz to 1 000 Hz and a
Fast Fourier Transform (FFηspect阳 m shall be made at each test point except shutoff. The vibration
measurements shall be made at the following locations
•
a)
on the bearing housing(s) or equivalent location(的 of all pumps , at the positions shown on Figures 31 through
33;
b)
on the shaft of pumps with hydrodynamic bearings with proximity probes , if the pump has provisions for
proximity probes
6.9.3.3
The FFT spectra shall include the range of frequencies from 5 Hz to 22 limes running speed (where 2
is the number of impeller vanes; in multistage pumps with different impellers , 2 is the highest number of impeller
vanes in any stage). If specified the plo吐ed spectra shall be included with the pump test results
NOTE
The discrete frequencies 1,0 , 2 ，口， and Z tîmes running speed are associated with various pump phenomena , and
are , therefore , of particular interest in the spectra

the

,
At 3 800 Im'm , the upper limi! 01 balance grade G2.5 produces a force due !o unbalance of 10% of rotor
weight , which means that unbalance does not have any material effec! on the rotor's operating shape
For rotors 四 hose flexi如 ility is high (see Table 17) , it is not practical 10 achieve and mainlain the rotor
straightness necessa 叩 for balance grade G 1
9.2.4.2.3
The mass eccentricity associated with balance grade G 1 is ve 叩
(0 ,00010 in) maximum for operation at 3 800 r/min , This has two consequences
small;
for example
2 ， 5μm
It is not practical to balance the components 10 be!ter than G2.5 (see 6.9 .4. 1) because the arbour effec!ively

The balance quali!y might not be verifiable if the rotor is dislurbed from its position on the balancing stand or

verify the accuracy of the balancing stand

(normative)
Hydraulic power recovery turbines
C.1 General
This annex applies to hydraulic power recovery turbines (HPRTs)
Power recove叩 is generally achieved by the reduction 01 liquid pressure , sometimes with a contribution Irom
vapour or gas evolution during the pressure reduction. A hydraulic power recovery turbine may be a pump
operated with reverse flow
C.2 Terminology
This International Standard uses terms that need to be changed or ignored when the standard is applied to
HPRTs. The direction 01 flow through the HPRT is the reverse 01 that through the pump. In such a context , the
word "pump" should be interpreted as meaning "HPR T", the term "pump suction" shoul岳阳 interpreted as
meaning the "HPRT outle t", and the term "purnp discharge" should be interpreted as meaning the "HPRT inlet"
C.3 Design
C.3.1
Li quid characteristics
•
C.3.1.1
The purchaser shall advise the HPRT manulacturer whether any p 。而on 01 the process stream
entering the HPRT can fiash to vapour and whether absorbed gas in the stream can evolve at any pressure less
than the inlet pressure
•
C.3.1.2
The purchaser shall specily the volume percentage 01 vapour or gas , or both , at the turbine outlet and
the pressure and temperature at which the vapour can fiash 。忏
C.3.1.3
1I known , the liquid composition , and the liquid and vapour (or gas) density versus pressu 陪， should
also be specified. It can be necessary to control the HPRT outlet pressure to limit the amount of liquid that fiashes
to vapour or the arnount 01 gas coming out 01 solu甘。 n
C.3.2 Seal唰，flushing sys!em
T 0 avoid shortening seal life , consideration shall be given to the evolution of gas and vaporization in seal-Ilushing
streams. If this potential exists , a seal fiush from other than the HPRT inlet is generally recommended
C.3.3 Overspeed trip
C , 3.3 , 1
An overspeed trip should be considered if the HPRT and other equipment in the train cannot tolerate
the calculated runaway speed (the maximum speed reached by the HPRT when υnloaded and subjected to the
worst combination 01 specified inlet and outlet conditions). Typically , overspeed trips are set in the range 01 115 %
to 120 % 01 rated speed. It is imp 。同ant to realize that runaway speed with inlet liquids rich in absorbed gas or with
liquids that pa 内 ially flash as they fiow through the HPRT can be several times higher than the runaway speed with
water. With such liquids , the runaway speed cannot be accurately determined
C.3.3.2
The risk 01 overspeed is reduced il the driven equiprnent, such as a pump or fan , cannot realistically
be expected to lose load. The risk is increased if !heà Fiven equiprnent is a generator , since a sudden
disconnection lrom electric power circuits unloads the HPRT. In the la t! er case , autornatic sensing and dummyload switching should be provided

C.3.3.3
Rotor systems that have low inertia and are subject to accidental unloading should be equipped with
a quick-acting brake 10 prevent damage Irom ove阳 peed
C.3.4 Dual drivers
NOTE
See Figures C.1 a) and b)
C.3 .4.1
1I an HPRT is used to assist another driver , the considerations in C.3 .4.2 through C.3 .4 .5 apply
C.3 .4.2
The main driver should be rated to drive the train without assistance Irom the HPRT
C.3 .4.3
An overrunning clutch (that is a clutch that transmits torque in one direction and Ireewheels in the
other) should generally be used between the HPRT and the train to allow the driven equipment to operate during
HPRT maintenance and to permit start-up 01 the train 如 elore the 刊 PRT process stream is lined up
C.3.4.4
Flow to the HPRT can vary widely and Irequently. 1I the flow drops to about 40 % 01 the rated 啊。Wτ
the HPRT stops producing power and a drag can be imposed on the main drive r. An overrunning clutch prevents
this drag
C.3.4.5
The 判 PRτshould
never be
placed 如etween
the main driver and the driven equipment
C.3.5 Generators
NOTE
See Figure C.1 c)
1I a generator is driven by an HPRT on a gas-rich process s甘eam ， the generator should be generously sized. The
output power 01 HPRTs can be as much as 20 % to 30 % or more above that predic恒 d by water tests , as a resull
。Ithe e忏'ects 01 evolved gas or ftashed liquid
C.3.6 Throttle valves
For most applications , valves used to control 何 ow to the HPRT should be placed upstream and near the inlet 01
theHPRT (see Figure C.1). Placement upstream allows the mechanical seals to operate at the outlet pressu 陪。f
theHPRT and , lor gas-rich streams , permits the gas to evolve , which increases the power output
C.3.7 Bypass valves
Regardless 01 the arrangement 01 the HPRT train , a lull-Ilow bypass valve with modulation capability should be
installed. Common control 01 the modulating bypass valve and the HPRT inlet control valve is normally achieved
by means 01 a split-Ievel arrangement (see Figure C.1)
C.3.8 Relief valves
T0 protect the HPRT outlet casing integrity and mechanical seals Irom possible do四nslream 如acιpressure
a reliel valve installed in the HP 只 T outlet piping circuit should be considered (see Figure C.1)

C.4 Testing
C.4.1 The HPRT should receive a performance test at the manufacturer's test facility. Hydraulic and mechanical
performance guarantees shall be based on water testing
C.4.2
Figure C.2 shows recommended test performance tolerances for HPRTs. The pump criteria given in the
main body of this International 8tandard are not applicable
C.4.3 Vibration levels lor HPRTs should meet the criteria for pumps given in the main body 01 this International
8tandard
C.4.4 It can 扫 e useful to verify the overspeed trip setting for the HPRT at the manufacturer's test facilit可
Determining the runaway speed during a water test may be considered , but this speed can be accurately
calculated once performance with water is known. Runaway speed for gas-rich steams cannot 如e determined by
water tests

Criteria for piping design
F.1
Horizontal pumps
F.1.1 Accepta扫 le piping con自 gurations should not cause excessive misalignment between the pump and driver
Piping configurations that produce component nozzle loads Iying within the ranges speci 在 ed in Ta 也 le 5 limit
casing distorlion to one-half the pump vendor's design criterion (see 6.3.3) and ensure pump shaft displacement
of less than 250 ~m (0β10 in)
F.1.2 Piping configurations that produce loads outside the ranges speci轩 ed in Ta也le 5 are also acceptable
without consultation with the pump vendor if the conditions specified in F.1.2 a) through F.1.2 c) as follows are
sa甘 sfied. Satisfying these conditions ensures that any pump casing distorlion is within the vendor's design criteria
(see 6.3.3) and that the displacement of the pump shaft is less than 38 。 μm (0 ,015 iη)
a)
The individual component forces and moments acting on each pump nozzle flange shall not exceed the
range specl古ed in Table 5 (T4) by a factor of more than 2
b)
The resultant applied force (FRSA , F RDA) and the resultant applied moment (MRSA , M RDA) acting on each
pump-nozzle flange shall satisfy the appropriate interaction equations as given in Equations (F 才) and (F.2)
[F RSA/(1 ,5 x FRS T4月十

(F.1)
[FRDN(1 ,5 x F RDT4月十 [MRDA/(1 ,5 x M RD了 4)] < 2
(F.2)
The applied component forces and moments acting on each pump nozzle fiange shall be translated to the
centre of the pump. The magnitüde of the resultant applied force , F RCA , the resultant appiied moment , M RCA ,
and the applied moment shall be limited by Equations (F.3) to (F.5). (The sign convention shown in
Figures 21 through 25 and the right-hand rule should be used in evaluating these equations.)

purchaser and the vendor
NOTE
!n order to evaluate the actual machine distortion (at ambient conditions) , the piping alignment checks required in
API RP 686 , Chapter 6 , should be performed. API RP 686 allows only a small fraction of the permi 忧ed disto币。 n resulting from
use of the va!ues from this annex
F.2 Vertical in-line pumps
Vertical in-line pumps (OH3 and OH6) that are supp。内 ed only by the attached piping can be subjected to
component piping loads that are more than double the values shown in Table 5 if these loads do not cause a
principal stress greater than 41 N/mm 2 (5 950 psi) in either nozzle. For calculation purposes , the section
properties 01 the pump nozzles shall be based on 8chedule 40 pipe whose nominal size is equal to that 01 the
appropna恒 pump nozzle. Equations (F.6) , (F.7) and (F.8) can be used to evaluate the principal stress , the
longitudinal stress and the shear stress , respectively , in the nozzles

Equation (F.7) is used to determine the longitudinal stress for the suction nozzle , O's
The applied F YSA load acting on the suction nozzle is in the negative Y direction and produces a compressive
stress; therefore , the negative sign on F YSA is used
σs = [才 ，27FYSA/(Do2 -D;与] + [10 200D o (MXSA 2 宁 MZSA 2)0， 5/(D o 4 - D;4)]

Thus , the suction nozzle loads are satisfactory

Thus , the discharge nozzle loads are too large. By inspection , if M XDA is reduced by 50 % to 1 356 N.m , the
resulting principal stress still exceeds 41 MPa. Therefore , the maximum value for M XDA is twice MXDT4 ' or

Thus , the suction nozzle loads are satisfactory
Discharge nozzle calculations are as follows
F .4 .4.2.2
For Schedule 40 pipe with a nominal size 013 in , Do = 3,500 , and D; = 3 ,068. Therefore ,

The materials for pump parts for each material class are given in Annex H
Specific materials recommendations should be obtained for 5e 刊 ces not clearly identified by the servωe descriptions
listed in this table
Cast iron casings (6.12.1.6) , if recommended for chemical services , are for non-hazardous locations only. Steel casings
should be used for pumps in services located near process plants or in any location where released vapour from a failure
can create a hazardous situation or where pumps can be subjected to hydraulic shock , for example in loading services
a
Oxygen content and. buffering of water should be considered in material selection
b
The corrosiveness of foul waters , hydrocarbons over 230 oC (450"町 acids ， and acid sludges can vary widely. Material
recommendations should be obtained for each service , The material class indicated above is satisfactory for many of these services , but
shall be verifjed. $-8 materials may also be considered for operating temperatures below 95 oC (200 OF)
c
If product corrosivity is low , class S-4 materials may be used for services at 231 oC to 370 oC (4肘。 F to 70日中)， $peci币 c material
recommendations should be obtained in each instance
d
AII welds sha l1 be stress-relieved.
e
UNS N08007 or Ni-Cu alloy pump material should be used
For seawater , produced water , formation water and brine services , the purchaser and the vendor should agree on the construction
materials that best suit the intended use
g
The vendor shall consider the effects of differential material expansion be阳een casing and rotor and confjrm suitability if operating
temperatures can exceed 95 QC (200 OF)
h
Materiais selected for low-temperature services shall meet the requirements of 6.12.1 ,6 and 6.12.4. Casting alloy grades LC 日， LC2
and LC3 are shown only for reference. Grades LC8 , LC2 and LC3 refer to 1$0 4991. C23.45BL , C43E2aL and C43l are equiva!ent to
A$TM A352/A352M , grades LCB , LC2 and LC3. Use equivalent materials for wrought alloys

Separation margins and damping
For both as咱newand 2x as-new clearances , the damping lactor versus separation margin between any bending
natural Irequency and the synchronous run line shall be within the "acceptable" region shown on Figure 1. 1. 1I this
condition cannot be satisfied , the damped response to unbalance shall be de!ermined (see 1. 1 .4)
In liquid.handling tu 巾 omachines ， the 白 rst assessment of a rotor's dynam 阻 characteristics is based on dampíng
separation margin , rather than amplification factor versus separation margin. Two factors account for this basis. First ,
the rotor's natural 什equencies increase with rotative speed , a consequence of the differential pressure across internal
clearances a!so increasing with rotative speed. On a Campbell diagram (see Figure L2) , this means that the c!oser separations
are between the running speed and natural frequencies rather than beìween the running speed and the critica! speeds
Because the amplifi也ation factor at the closer separations is not 阻 lated to synchronous (υnba!ance) excitation of the rotor , it
can be developed only by an approximate calculation based on the damping. Second , emp!oyíng damping allows the
spec!白 cation of a minimum value for natural frequency to running speed ratios from 0 ,8 to 0 ,4, thereby assuring that the rotor is
free from significant subsynchronous vibration

Shop verification of rotor dynamic characteristics
1I specified , the dynamic characteristics 01 the rotor shall be verified during the shop test. The rotor's
actual response to unbalance shall be the basis lor confirming the validity 01 the damped lateral analysis. This
response is measured during either variable-speed operation Irom raled speed down to 75 % 01 the 币 rst critical
speed or during coast-down. 1I the damped response to unbalance was not determined in the original rotor
analysis (see 1. 1 句， this response shall be determined lor a pump with new clearances handling water belore
proceeding with shop verilication. The test unbalances shall be vectorially added in phase with the residual
unbalanceιat locations determined by the manulacturer (usually at the coupling and/or thrust collar)
1.2.1
NOTE
The princípal objective of shop verification by response to unbalance is to verify the existence of a critical speed
(vibration peak) within the tolerance of the calculated value , or , if the analysis predicted a highly damped critical speed , the
absence of a vibration peak within tolerance of the calculated value. Shop verificatíon by this method is feasible only for pumps
that have sleeve bearin臼 s and that are furníshed with proximity probe pairs at each journal bearing
1.2.2
The magnitude and location 01 the test unbalance(s) shall be determined 什om a calibration 01 the rotor's

Determination of residual unbalance
J.1
General
This annex describes the procedure used to determine residual unbalance in machine rotors. Although some
balancing machines may be set up to read out the exact amount 01 unbalance , the calibration can be in erro r. The
only sure method 01 determining residual unbalance is to test the rotor with a known amount 01 unbalance
J.2 Terms and definitions
J.2 , 1
residual unbalance
amount 01 unbalance remaining in a rotor after balancing
NOTE
UnJess otherwise specîfied , residua! unbalance is expressed in
gram 盼m iIJ imetres
(g.mm) [ounce-inches
(oz.j的i
J.3 Maximum allowable residual unbalance
J.3.1
The maximum allowable residual unbalance per plane shall
be 叶 etermined
Irom Table 19
J.3.2
1I the actual static load on each journal ís not known , assume that the total rotor mass ís equally
the bearín ♀s. For example , a two也earíng rotor wíth a mass 01 2 700 kg (6 000 Ib) can be assumed
to ímpose a mass 01 1 350 kg (3 000 Ib) on each journal
supported 如y
J.4 Residual unbalance check
J.4.1 General
J .4.1.1
When the balancing machíne readíngs índícate that the rotor has been balanced to wíthín the
specílíed tOlerance , a resídual unbalance check shall be performed belore the rotor ís removed 什。 m the balancíng
machíne
•
J.4.1.2
To check the resídual unbalance , a known tríal mass ís attached to the rotor sequent剧 Iy ín 6 (or 12 , íl
specílíed by the purchaser) equally spaced radíal posítíons , each at the same radíal distance. The check ís run ín
each correctíon plane , and the readings in each plane are plotted on a graph using the procedure spec出 ed ín
J .4 .2
J.4.2 Procedure
J .4.2.1
Select a tríal mass and radius that provídes between one and two times the maximum allowable
residual unbalance [that ís , il Umax is 1 440 g.mm (20z.ín) , the tríal mass ís expected to cause 1 440 g.mm to
2880 g.mm (2 oz.ín to 4 oz.ín) 01 unbalance]
J .4.2.2
Startíng at the last known heavy spot ín each correctíon plane , mark off the specílíed number 01 radial
posítíons (6 or 12) in equal (60' or 30') increments around the roto r. Add the trial mass to the last known heavy
spot ín one plane. 1I the rotor has been balanced very precisely and the final heavy spot cannot 扫 e determined ,
add the lrial mass to any one 01 the marked radial positions
J.4.2.3
To verífy that an appropríate trial mass has been selected , operate the balancing machine and record
the readíng on the meter. 1I the reading is at the upper limi! 01 the meter range , a smaller trial mass shall be used

1I there is little or no meter reading , a larger 甘ial mass shall 也 e used. Little or no meter reading generally indicates
that the rotor was either not balanced correctly , or the balancing machine is not sensitive enough , or the balancing
machine is laulty (e.g. a faulty transducer). Whatever the error, it shall be corrected before proceeding with the
residual check
J .4.2.4
Locate the mass at each of the equally spaced positions in turn , and record the amount of unbalance
indicated on the meter for each position. Repeat the initial position as a check. AII verification shall be performed
using only one sensitivity range on the balance machine
J .4.2.5
Plot the readings on the residual unbalance work sheet and calculate the amount of residual
unbalance (see Figures J.1 and J .2). The maximum meter reading occurs when the trial mass is added at the
rotor's heavy spot; the minimum reading occurs when the trial mass is located opposite the heavy SpOt. Thus , the
plotted readings are expected to form an approximate circle (see Figures J.3 and J.4). An average of the
maximum and minimum meter readings represents the effect of the trial mass. The dis\ance of the circle's centre
from the origin of the polar plot represents the residual unbalance in that plane
Repeat the steps described in J .4.2 .1 through J .4. 2.5 for each balance plane. 1I the specified
maximum allowable residual unbalance is exceeded in any balance plane, the rotor shall be balanced more
precisely and checked again. If a correction is made to any balance plane , the residual unbalance check shall be
repeated in all planes
J.4.2.6
J .4.2.7
For progressively balanced rotors , a residual unbalance check shall be performed after the addition
and balancing of the 自由t rotor component , and at the completion of balancing 01 the entire rotor , as a minimum
NOTE
This ensures that time is not wasted and rotor components are not subjected to unnecessary material removal in
attempting to balance a multìple-component rotor with a faulty balancing machine

Shaft stiffness and bearing system life
K.1 Guideline on shaft stiffness for overhung pump types OH2 and
0抖 3
K.1 presents a standardized method lor calculation 01 overhung pump shaft Ilexibility index. 1I specified
(see 9.1.1.3) , the shaft flexi 如 ility index shall be calculated by the vendor in accordance with this subclause and
stated on the data sheet
The design and operation requirements lor overhung pump rotors are detailed in several areas 01 this
In!ernational Standard. This subclause lists !hese requirements and establishes a standardized process 01
calculating a shaft 刊 exibility index that may be used to evaluate these latter parameters and to establish a
baseline lor the comparison 01 shaft flexibility
For a sha性。1 two diameters , D 才 under the seal sleeve and D 2 be!ween the bearings (see Figure K.1) , the shaft
stiffness is inversely proportional to what is generally termed the shaft Ilexibility index , SFI or ISF' delined as given
in Equation (K 才)
ISF ~ L 13ID 14 + L才 Li ID 2 4
whereL 才 is
(K.1)
the overhang (centreline 01 impeller to line bearing) and L 2 is the bearing span
In rotor designs typical 01 relinery pumps , D 2 > D才 and L2 < L1' the second term accounts lor only about 20 % 01
the total value oIISF , so the convention is to assess overhung pump shaft stiffness using a shortened expression
as given in Equation (K.2)

The shortened calculation for JSF ' Equation (K .2), was used extensively by refiners in the 1970s and 80s t。
compare overhung pump rotor stiffness and assign a maintenance cost factor to the price 01 pumps whose ISF
was some multiple , typically 1,2 , 01 the lowest value 01 the pumps 0忏ered lor the service. That practice led to the
development 01 the higher stiffness rotors necessary to achieve longer pump mean time belween repair (MTBR)
and in the 1990s, lower sha作 seal leakage lor reduced volatile-organic心。 mpound (VOC) emissions. Because the
assessments were applied to pumps lor a given application , the comparison was belween pumps 01 similar size
To provide general guidance on values 01 I SF , it is , therelore , necessary to relate ISF to pump size
Overhung-refinery-pump bearing Irames are designed in discrete sizes. The shaft for each is , therelore , designed
lor the maximum torque , impeller mass and impeller radial load (static and dynamic) 01 the largest liquid end the
Irame is intended to serve. Impeller mass is signilicant in that it is necessary lor the rotor's first dry bending critical
speed to be 120 % 01 the pump's maximum continuous operating speed (see 6.9.1.2). At the same time ,
defiection at the seal laces produced by radial thrust shall not exceed 50μm (see 0,002 in) (6.9.1.3)
The loads imposed on the shaft are directly related to the size 01 the impeller and , hence , to the Ilow, total head
and speed 01 the pump. This allows the definition 01 a "size" lactor , K" as given in Equation (K.3)
,
K = (Q x H) /N
(K.3)
where
Q
is ftow at BEP 01 maximum diameter impeller;
H
is the corresponding total head;
N
is the rotative speed
,
The size lactor is related to torque. A log-Iog plot 01 ISF versus K lor various overhung pump designs ranging
Irom 25 kW to 350000 kW (35 hp to 500000 hp) , with the hi臼 her value for large pump-turbines , shows that the
data lor modern designs lall about a straight line; see Figures K. 2 and K.3. The line 01 best lit through the high
side 01 the data is also shown
丁 he
high-side lines 01 best fit is defined by Equation (K .4) in 81 units and by Equation (K.5) lor U8C units
,
I SF .S1 = 32 x K -O ,76
(KA)
,
(K.5)
JSF ,usc = 6 200 x K -O ,76
Equations (K .4) and (K. 5) cover relinery pumps whose rotors , at the limit 01 each Irame , reportedly just meet the
static de刊 ection and rotor dynamics requirements 01 this International 8tandard based on rated speeds up t。
3 600 rpm. The liquid-end 吐esigns generally have double volutes lor all pumps 01 100 mm 怜 in) discharge and
large r. In some cases the designs may be limited to 3 000 rpm
Figures K.2 and K. 3 or Equations (KA) and (K.5) can 如 e used to make a first assessment of the rotor stiffness 01
a given overhung pump design or a number 01 similar designs lor a given applicat旧 n. An overhung pump whose
ISF is more than 1,2 times the chart or equation value is cause to seek justification 01 the design from the pump

K.2 Bearing system life considerations for OH2 , OH3 , BB1 , BB2 and BB3 pumps
K.2 presents a method of calculating bearing system life. 1I specified , bearing system life calculations shall be
furnished (see 6.10.1.6)
Bearing system life (the calculated lile 01 the combined system 01 bearings in the pump) shall be equivalent to at
least 25 000 h with continuous operation at rated conditions , and at least 16 000 h at maximum radial and axial
loads and rated speed. This clause contains a discussion of these requirements
This International 8tandard (AN81/API 8td 610/1 8013709) requires that pumps be desi♀ ned for 20 years life and
3 years continuous service. Thus , it is necessary that the bearing "system ," not just the individual bearings alone ,
be designed for a minimum lile 01 3 years. This is not normally a problem and most user reliability statistics show
that bearing lile is not a major determinant oloverall pump reliability. In cases where bearing lile is an issueτthe
root causes are usually related to lubrication
Historically , this International 8tandard has required that "individual" bearings be designed for a minimum L 叩 h life
0125000 h and 16000 h atth.e maximum ~adial and axialloads and rated sPEled. Bearing~system lile , L 0h ,sys ,ds

EXAMPLE 1
If a pump has two bearings of equal L 'Oh life (not ve 叩 likely) and a bearing system life of 25000 h ，白e
individual bearings would have a L叩 h life of approxímate!y 37 5日 o h. Note that because rollìng-e!ement bearings are
manufactured in standard sìzes , ìt is unlikely that any particular pump wou!d have a calcu!ated L 10h life of exactly 37 500 h for
both bearîngs in the system
EXAMPLE 2
If one bearing has a ca!cu!ated L 10h life of 100 000 h (not unusua!) , it is necessary for the other bearing in the
system to have a calculated L 10h life of on 阳 about 25 700 h to give a bearing system life of approximately 25 000 h
OH2 , OH3 , and to a lesser extent , BB1 , BB2 and BB3 , pumps are not totally "engineered pumps" in that each
component is not necessarily "designed" for a particular purchaser's order requirements. They are generally
"design lines of pumps" , or pumps that are "pre-engineered" 也y the manufacturer to meet the requirements of this
International Standard within a particular range of operating conditions for specific applications. This is particularly
true for BB designs that can have multiple rotor and volute designs within one case pattern using several bearing
housing and seal chamber designs. These "pre-engineered" pumps may then be modi白 ed ， as required , to meet
unique applications and purchaser requirements. In the design/product line development process for these pumps ,
the manufacturer chooses a set of extreme conditions within which he desires to sell "standard pumps". These
conditions va叩 according to the manufacturer's experience with the breadth of services his customers require
These conditions can 扫e chosen to encompass 98 % of all refinery services into which he has sold pumps in, say,
a 10 year period
Once the range of operating conditions has been established , the manu 饱 cturer chooses a number of bearingframe sizes. For most pump manufacturers , this 皑白 ther three or four sizes for these types of pumps. The
manufacturer then matches his available or anticipated se!s of hydraulics to the various bearing frames. For each
bearing frame , there is a set of hy吐 raulics that imposes the greatest loads on the bearings and frame. For this se!
of hyd陆 ulics ， it is necessary that the minimυm 扫earing system life meet the 陪quirements of this Interna柱。ηal
Standard 抖。wever ， it is completely possible that there are sets of operating conditions or service parameters
(such as high suction pressure , low running speed , operating pumps outside the preferred or allowable operating
regions) where this pump does not meet all the requirements of this International Standard. For these conditions ,
the manufacturer has a number of options, including modifying the pump design to meet all the requirements,
limiting the pump operating range or negotiation with the purchaser to accept a slightly lower bearing-system lile
in order to reduce cost or improve overall bearing performance. This can be beneficial if operating conditions are
such that bearing loads vary significantly and can result in loads that are 100 low for optimal bearing performance
For all other sets of hydraulics, the bearing loads are lower. The equation for bearing life , L 1Oh' as a function of
load is given by Equation (K.7) , taken from ISO 281:2007 , Equation (4)
,

Examining Equation (K.6) , one can see that lor a given bearing , with a given load , a reduction in applied load 01
10% results in an increase in bearing lile 01 approximately 37 %. This means that the calculated bearing-system
lile lor all pumps with a given bearing frame is much greater than the bearing-system life requirement 01 this
International Standard that is applied to the largest set 01 hydraulics for that bearing frame. Further , for the largest
bearing Irame , the system life is also greater il the impeller is at less-than-maximum diameter , il the specilic
gravity is low or il the suction pressure is lower than that used in the limiting case. Further , because bearings with
the smallest size having ratings that exceed the calculated loads are chosen , even the largest set 01 hydraulics
can well have a much higher calculated bearing-system 哥也 This gives some insight as to why the historical
requirement 01 25 000 h L 10h life for individual bearings has not been a problem
It is noted that there are rolling element bearings much larger and with much higher dynamic load ratings that are
used in pumps compliant with this International Standard. The application of rolling-element bearings is limited by
bearing size and the speed of rotation. It has been found by the pump industry that large bearings running at twopole speeds (3 000 and 3600 nominal r/min) tend to run "hot" and can exceed the maximum bearing temperature
requirements 01 this International Standard. As a result 01 this , all manulaclurers limit angular-contact thrust
bearings to about 7 315 or 7 3 丁 6 sizes for two-pole machines. These correspond to shaft sizes of 75 mm and
80 mm (2 ,95 in and 3 , 15 in) , respectively
While hot running is detrimental to lubricant and bearing life , the most problematic issue is ball skidding in lightly
loaded bearings. 1I a pump manulacturer applies larger bearings lor each Irame size , it is necessary that he lim民
the application 01 each bearing frame to hydraulics that provide bearing loads su忏icient to minimize ball skidding
This means additional bearing-Irame sizes can be required to cover all pump sizes in a given product line , thus
reducing component production volume, interchangeability and stocking oppo 同 unities
The issue of bearing-system Iife is an application Ii mitation lor pumps 01 "standard designs"

Pump datasheets and electronic data exchange
N.1 Pump data sheets
This annex c。ηtains typical datasheets lor use by the purchaser and the vendor as shown in Figure N.1 and
Figure N.2. The datasheets , in both SI and USC units , are copies 01 the electronic lorm 01 the datasheets
(Microsoft Excel Spreadsheets). In the electronic lorm , selection 01 the units on the datasheet will automatically
change all the units on the datasheet to the units selected. Note however , that this electronic datasheet does not
contain in-built calcula甘 ons ， therelore changing the units will not impact any data entered onto the datasheet
The datasheet is intended to be used in its electronic lormat and as such , there are numerous cells that contain
dropdown selections. As these selections are not presented to the user until the cell is selectedτthe copies in this
document indicate which cells contain a drop-down selection in the shaded areas. Another leature 01 the
electronic datasheet is that when the user selects a data entry cell ，汗 there is a cross relerence back to the
standard a pop-up box will appear indicating the relerence parag阻 ph and some or all 01 the content 01 the
relerenced paragraph
To assist the reader a document map (See Figure N.3) , which is basically the datasheet less all content , has been
prepared which lists the content 01 the drop-down selection at each line as applicable. In addition to the dropdown list , there are some lines with numbers listed on the left-hand side 01 the area. These numbers are the
numbers 01 the crossed relerenced paragraphs , which pop-up as mentioned above
In all instances the document map lists the inlormation on the same line as the electronic datasheet
N.2ξlectronic data exchange (EDE)
The inlormation contained in pump data sheets may also be transmilted digitally rather than via a conventional
data sheet lormal. This is suitable when pump purchaser and supplier have systems that can process digital
information rather than paper-based data sheets. Direct electronic transfer can be achieved with a transfer
protocol that is adopted by both purchaser and supplie r. It is necessary that this transler protocol also be
commercially neutral for it t。如e accepted 扫y all parties. Such a method improves the operating efficiencies 01 扫oth
parties il their internal data systems can importlexport via this neutral protoco l. Examples 01 these systems
include
a)

Those interested in adopting electronic data exchange (EDE) are encouraged to reference the EDE technology
and implementation standard , BSR/HI50.7 , for the digital transfer of centrifugal pump data. This standard
provides implementation details and examples towards adopting EDE that is suitable for
ANSI/API Std 610/lS0 13709 centrifugal pump data. Additional interpretive information is also available at
http://l!ýWW. pumps.oro/ede
BSR/HI 50.7 was developed and suppo时ed by the Hydraulic Institute and the FIATECH automating equipment
information exchange (AEX) project , in coope旧tion with the AP I. Information on the EDE technology and the AEX
XML schemas is available on line at www.fiatech.oro/aex.html
A complete listing of all data fi阻 Ids in the electronic data sheets N.3.1 through N.3.3 and their corresponding XML
structures are found in BSR/HI 50.7 w矶 W.DumDS.ora/ede or via FIATECH at 1Mww.fiatech.oro/aex.html
