NFPA standards
Fire DNF, Fire HSF
Introduction to the NFPA
Underwriters Laboratories
The National Fire Protection Association (NFPA) is an
international, non-profit organisation of fire safety
professionals. The NFPA headquarters is located in the
USA.
The organisation creates and maintains minimum
standards and requirements for fire prevention and
suppression activities, training, equipment and other
life-safety codes and standards.
See the NFPA homepage: http://www.nfpa.org.
The "UL File Number" of a product can be used to look
up a certificate at the UL homepage.
See www.ul.com > Online Certifications Directory.
NFPA 20
The DNF, HSF bare shaft pumps comply with the
NFPA 20, Standard for the Installation of Stationary
Fire Pumps for Fire Protection. The standard covers
systems for commercial and private buildings.
Standards approval process
TM03 5392 3606
TM03 5369 3606
The pumps have been tested and certified by
FM Global (FM) and Underwriters Laboratories Inc.
(UL) to comply with the requirements of the NFPA 20.
Compliance with the requirements is indicated by the
FM and UL marks affixed to the pumps. See fig. 1.
APPROVED
Fig. 1 FM and UL marks
Other NFPA standards
These standards are also of relevance to the products
described in this data booklet:
• NFPA 13. Installation of sprinkler systems
• NFPA 25. Standard for the inspection, testing and
maintenance of water-based fire protection systems
• NFPA 70. National Electrical Code.
See the NFPA homepage: http://www.nfpa.org.
FM Global
The FM Global (FM*) is a mutual commercial and industrial property insurance and risk management organisation, located in the USA with offices worldwide.
* FM is short for Factory Mutual.
FM tests and approves industrial and commercial products in compliance with its own standards, or other
nationally recognised requirements.
The FM Approved mark indicates that the product complies with the required standards. See fig. 1.
See the FM homepage: www.fmglobal.com.
4
UL does not "approve" any product. Rather it tests
product samples and permits acceptable products to
carry the UL mark, as long as they remain in conformity
with the standards and with the samples tested to those
standards.
UL maintains a list of more than 100,000 products it has
tested. The database with the UL-listed products is
available online to the public.
The NFPA standards are often revised, due to new
information and technical equipment.
FM
Underwriters Laboratories Inc. (UL) is an independent,
non-profit, product-safety testing and certification
organisation located in the USA.
Grundfos tests the pumps and fills in the application
forms for each individual pump size. We submit this
documentation to FM and UL:
• Expected pump performance, including total head,
power requirements and efficiency versus flow
characteristics.
If different impeller diameters are used to obtain the
rated head for the pump to be examined, complete
details must be provided concerning performance
specifications to be evaluated.
• Calculations to determinate shaft size, casing bolt
size and anti-friction bearing life.
• General assembly drawings, a complete set of manufacturing drawings, materials lists and physical
property specifications, expected marking format,
brochures, sales literature, specification sheets, installation, operating and maintenance procedures.
If the application forms are accepted, FM and UL will
attend the final test at the Grundfos premises.
If the evaluation of the test results is positive, FM and
UL issue a certificate of compliance of the pump with
the standards specified.
If a pump component is replaced after the certificate of
compliance has been issued, representative samples
of the pump may need to be re-tested.

System design
A fire system typically consists of three pumps: one
pressure pump (jockey pump) and two fire pumps, one
duty and the other acting as standby. Each of the fire
pumps is capable of achieving the required
performance.
Systems with only one fire pump or more than two fire
pumps are, however, also seen.
Operation
The jockey pump maintains pressure in the system and
compensates for any loss of pressure caused by leaks
and thus prevents the duty pump from starting unnecessarily. The jockey pump has two pressure levels:
• a low pressure level to start the jockey pump
• a high pressure level to stop the jockey pump.
In case of further decrease of system pressure due to
fire (i.e. sprinkler opens), the duty pump starts. In case
this pump fails to start or breaks down, the standby
pump will start.
8
Pos.
1a
The duty and standby pumps are not powered by the
same source. This ensures that if one pump fails, for
example due to fire damage, the other will operate. The
pumps are controlled by pressure sensors.
Although individually designed for the specific installation, each fire unit must comply with NFPA standards.
Fire pumps
FM-approved and UL-listed Grundfos end-suction and
split-case pumps are designed for the distribution of
water in automatic sprinkler and standpipe systems.
They are operated in case of fire and during tests.
Materials
Impeller, wear rings, guide or diffusion vane rings,
lantern rings, bottoms of stuffing boxes, interior nuts,
linings of stuffing-box throats, glands, gland nuts and
drain plugs are made of corrosion-resistant material.

Flow vs. pressure
The approval/listing of the pump is based on a certain
rated flow, indicated by the solid line in the curve
charts. The pump must be able to supply not less than
150% of the rated flow (broken line) and still be able to
provide at least 65% of the total rated pressure. See
fig. 3 and the example below.

Fig. 3 Flow vs. pressure
Example
The pump complies with a flow requirement of 750 gpm
(170 m³/h). At this flow, the pump delivers a pressure of
44 psi (31 mH). To be FM-approved/UL-listed, the
pump must comply with these requirements:
Rated flow (100%):
750 gpm (170 m³/h)
Minimum flow supplied by the pump (150%):
1125 gpm (256 m³/h)
Rated pressure (100%):
44 psi (31 mH)
Minimum pressure supplied by the pump
(65%):
28 psi (31 mH)
At 150% of the total rated flow, the pump delivers a
pressure of 34 psi (24 mH). This means that the pump
complies with the requirements.
Rated pressure (100%):
44 psi (31 mH)
Minimum closed-valve pressure (101%):
44 psi (31 mH)
Maximum closed-valve pressure (140%):
61 psi (43 mH)
The pump has a closed-valve pressure of 53 psi
(37 mH). This means that the pump complies with the
requirements.
Engine power rating
To ensure that the engine is capable of operating the
pump at any time, the NFPA demands that the manufacturer determines the maximum power required at a
certain duty range. The maximum power occurs when
there is no increase in power with an increase in the
flow. See fig. 5.

Diesel engines
Engines must be listed for fire pump operation. The
engines must be of the compression-ignition type.
Jockey pumps
Grundfos CR pumps are used as jockey pumps,
maintaining the pressure. Under normal conditions, the
jockey pump is activated by the low-pressure switch as
a result of small leakages or if one or more sprinklers
are activated.
The jockey pump is not subject to any specific NFPA
requirements.
Control panel
The control panel for the fire pumps must comply with
NFPA 20 requirements. In addition, the cabinet must be
listed by UL and ULC and approved by FM and CSA.
The control panel is
• painted with RAL 3000 (red)
• housed in a NEMA Type-2 drip-proof enclosure.
The control panel is suitable for wall mounting or floor
mounting. See "Type keys", page 16.

Stuffing box
Impeller
The stuffing box is made of braided packing rings.
Braided material ensures a long service life of packing
rings and protects the pump shaft (sleeve). The packing
rings are installed symmetrically with parallel faces to
prevent tilting.
The closed impeller made of bronze has double-curved
blades with smooth surfaces for high efficiency.
TM03 4680 2506
Materials
PTFE-impregnated fibre packing rings and EPDM Orings in pump housing.
Type of barrier fluid
• DNF: internal barrier fluid

• HSF: external barrier fluid.
Fig. 19 Double-suction impeller for an HSF pump
The impellers are hydraulically balanced and
dynamically balanced together with the shaft. The
hydraulic balancing compensates for axial thrust.
The direction of rotation of the impeller is clockwise
when viewed from the engine.
TM03 4596 2306
The impellers are adapted to the duty point required by
the customer.

Surface treatment
Cast iron parts are coated with a protective primer
(thickness of 30 μm ± 5 μm).
The part is cleaned with an organic solvent and finally
spray-painted with red two-component paint,
RAL 3000. The thickness of the dry coating is
30 μm ±5 μm.
Test pressure
Before delivery, the pumps are hydrostatically tested
for 5 minutes to 1.5 times the sum of the closed-valve
pressure plus the maximum permissible suction head,
1.5 x (Pmax + Pmax suction), but not less than 250 psi.
Test liquid: Water at 20°C (68°F).

Engine type and rating
Starting system
The compression-ignition diesel engine must be
approved/listed for fire pump operation. The mark of the
listing laboratory (FM and/or UL) is displayed on the
engine nameplate showing compliance with the performance ratings and functional requirements.
The engine is provided with two storage battery units.
At 4.5°C (40°F) each battery must have twice the
capacity sufficient to maintain a 3-minute attempt to
start cycle (6 consecutive cycles of 15 seconds cranking and 15 seconds rest).
The engines are rated at standard SAE conditions at
752.1 mmHg barometer and 25°C (77°F) inlet air temperature. (SAE = Society of Automotive Engineers.)
Two systems for recharging the batteries are used:
Listed engines have an additional 10% power reserve
of the pump’s maximum requirement.
• An engine-driven generator/alternator recharging
the batteries when the diesel engine is running.
This system is completely independent of external
resources.
Instrumentation and control devices
• Automatically controlled charger power supplied
from the building and fitted in the control panel.
The local instrumentation on the engine is shown in
fig. 21. The control panel monitoring the fire system is
described in a different data booklet.
Engine cooling
The engine cooling system is of the closed-circuit heat
exchanger type.
XXXXXXXXX
3
TO START ENGINE
1
Both chargers must be listed for fire pumps.
1.Position MODE SELECTOR switch to MANUAL RUN.
Cooling water is piped through a threaded, rigid pipe
from the pump discharge to the inlet of the heat
exchanger. The wastewater can be discharged into a
visible, open waste cone or go back to a suction reservoir.
2.Lift and hold MANUAL CRANK #1 until engine starts, or release
after 15 seconds. If unit fails to start, wait for 15 seconds,
use MANUAL CRANK #2 and repeat step.
2
3.If COOLING WATER is not flowing or engine TEMPERATURE is too HIGH,
open cooling system manual by-pass valve.
TO STOP ENGINE
1.Push and hold MANUAL STOP until Engine Stops.
2.Return MODE SELECTOR switch to AUTOMATIC and MANUAL STOP position,
engine will stop.
4
3.Close cooling system manual by-pass valve.
IMPORTANT
DO leave
NOT the MODE SELECTOR switch in the MANUAL RUN position
during AUTOMATIC operation.
OVERSPEED RESET

The heat exchanger has the best efficiency at 60 psi.
Engine exhaust
Each engine must have an independent exhaust system.
A flexible connection is used between the engine and
the exhaust pipe to provide thermal expansion and to
isolate engine vibration to the rest of the exhaust run.
The flex connector should not be used for misalignment.
The exhaust system must be building-supported, not
engine supported.
The engine must have:
Fuel arrangement
• a governor cable for regulating the engine speed
within a range of 10% between shut-off and maximum load
The fuel tank outlet must be placed above the engine
fuel inlet.
• an overspeed shut-down device arranged to shut
down the engine at a speed approximately 20%
above the rated engine speed.
The fuel tank must be sized for 5.1 l/kW (1 gallon/hp)
plus 10% (5% for expansion and 5% for sump).
In zones with temperatures below 0°C (32°F), the fuel
tank shall be located in the pump room.
Fuel supply and return lines shall be flame-resistant,
reinforced flexible hose.

Operating conditions
Pump unit location
Fire DNF, Fire HSF
Inlet pressure
The pump unit is designed for installation in a nonaggressive and non-explosive atmosphere.
Maximum inlet pressure
The inlet pressure is limited by the maximum operating
pressure. The maximum inlet pressure is 100 psi
(approx. 7 bar).
Ambient temperature
The ambient temperature must not exceed +25°C
(77°F).
If the ambient temperature exceeds +25°C (77°F) or if
the engine is installed more than 90 metres (300 ft)
above sea level, the engine power must be derated
according to figures 23 and 24. It may be necessary to
use an oversize engine with a higher output.
Minimum inlet pressure
The pressure at the pump suction flange must be 0 bar
(atmospheric pressure) or higher (positive inlet pressure) in any operating condition.
Ventilation requirements
The inlet louvre and ventilation system must
• ensure that the temperature in the room does not
exceed 49°C (120°F)
P2
[%]
100
• supply adequate air for engine combustion.

Adequate air for ventilating radiated heat; both engine
and exhaust system.

Piping
Alignment
When installing the pipes, make sure that the pump
housing is not stressed by the pipework.
The engine crankshaft and the pump shaft must be parallel aligned. We recommend a 3-degree disalignment
between the PTO shaft and the engine/pump shaft to
ensure even wear of the joints in the PTO shaft.
The suction and discharge pipes must be of an adequate size, taking the pump inlet pressure into account.
Install the pipes so that air locks are avoided, especially
on the suction side of the pump. See fig. 26.
The pump/engine alignment may be affected during
transport. Always check alignment after the pump has
been installed.
TM00 2263 3393
Take care to align carefully as this will increase the
working lives of the coupling, bearings and stuffing
boxes.
Fig. 26 Pipe sections
Fit isolating valves on either side of the pump to avoid
having to drain the system if the pump needs to be
cleaned or repaired.

TM03 5499 4006
Make sure the pipes are adequately supported as close
to the pump as possible, both on the suction and on the
discharge side. The counter flanges should lie true
against the pump flanges without being stressed; otherwise, the pump will be damaged.

Curve conditions
The tables above the curve charts on the following
pages show:
Selection of pumps
• the FM-approved and UL-listed pressure range
• the Clarke range of engines.

JU4H-UF14
• The curves show pump performance with different
impeller diameters at the nominal speed.
Calculation of total head
The curve charts show curves at 5 psi pressure intervals, in this example at 65, 70 and 75 psi.
If a duty point at 65 psi is required, the pump will only
be FM approved.
Engine type
• Tolerances according to ISO 9906, Annex A.
• The curves apply to the pumping of water at a temperature of +20°C (68°F) and a kinematic viscosity
of 1 mm2/s (1 cSt).

The guidelines below apply to the performance curves
shown in the curve charts, pages 38 to 73.
The total pump head consists of the height difference
between the measuring points + the differential head +
the dynamic head.

The engine type, JU4H-UF14, covers the whole pressure range. For more specific information on the
engines, see "Engine construction", pages 27 to 30,
and "Diesel engine data", pages 25 to 26.
Hstat: Differential head between the suction and the
discharge side of the pump.
Hdyn: Calculated values based on the velocity of the
pumped water on the suction and the discharge
side of the pump.
Performance tests
The requested duty point for every pump is tested
according to ISO 9906, Annex A.
If the customer requires either more points on the curve
to be checked or certain minimum performances or certificates, individual measurements must be made.
FM/UL certificates
The pump order includes a test certificate confirming
the required QH performance. See page 5.

contains
• technical data
• curves (QH, Eta, P1, P2, etc) which can be adapted to the density and viscosity of the pumped liquid and show the number of
pumps in operation
• product photos
• dimensional drawings
• wiring diagrams
• quotation texts, etc.
Literature
In this section you can access all the latest documents of a given
pump, such as
• data booklets
• installation and operating instructions
• service documentation, such as Service kit catalogue and
Service kit instructions
• quick guides
• product brochures, etc.

This section is based on different fields of application and installation examples, and gives easy step-by-step instructions in how to
• select the most suitable and efficient pump for your installation
• carry out advanced calculations based on energy consumption,
payback periods, load profiles, life cycle costs, etc.
• analyse your selected pump via the built-in life cycle cost tool
• determine the flow velocity in wastewater applications, etc.
Replacement
In this section you find a guide to selecting and comparing replacement data of an installed pump in order to replace the pump with a
more efficient Grundfos pump.
The section contains replacement data of a wide range of pumps
produced by other manufacturers than Grundfos.
Based on an easy step-by-step guide, you can compare Grundfos
pumps with the one you have installed on your site. When you have
specified the installed pump, the guide will suggest a number of
Grundfos pumps which can improve both comfort and efficiency.
CAD drawings
In this section it is possible to download 2-dimensional (2D) and 3dimensional (3D) CAD drawings of most Grundfos pumps.
These formats are available in WebCAPS:
2-dimensional drawings:
• .dxf, wireframe drawings
• .dwg, wireframe drawings.
3-dimensional drawings:
• .dwg, wireframe drawings (without surfaces)
• .stp, solid drawings (with surfaces)
• .eprt, E-drawings.
