at rated vacuum and temperature'
The dielectric properties of oil may vary depending upon the content of gas,
moisture, suspended priti.i.t and contaminants' Even new oil absorbs gas and
moisture r,r,hile in storage. Therefore, oil is to be treated before use. Degassing of oil is
also necessary perioaicatty, during use, because dielectric properties will be affected
due to the absorption of gas and moisture in service at different weather conditions.
The transformer oil filtration plant is designed for 6000 LPH capacity edge

INTRODUCTION:
lntroduction & Operation: 'ROTODEL' Rotary Gear Pump type 'HG' is a simple two piece
construction, cast iron pump for general purpose viscous liquid transfer application. The pumping
element s a set of single helical modified profile gear shrunk fitted on hardened & ground shaft
supporled on either side on self-lubricated sintered bronze bush bearing, rotating in a closed
tolerance casing. The space between the tooth gap & casing forms a cavity, which broadly
carries the liquid from the suction bay to discharge port. When the pair of gears opens on the
suction side vacuum is created with assistance of viscous Iiquid film enabling the liquid to enter
the pumping chamber with the assistance of atmospheric pressure, thus this pump are also selfprimrng The incoming liquid feels up the tooth cavity, which broadly moves on the periphery to
the dtscharge side & is pushed foruuard over coming the backpressure thus developing the
pressure n this process some liquid always escapes on the suction side throe the internal
clearance causing slip, which depend upon the internal clearance, the workmanship the viscosity
of the liqurd & the differential pressure. Some amount of slip is always desirable as it helps in
lubncat ng the gear faces, the bush bearing etc.

A posttive displacement pump do not develop pressure on it's own but has capability to over
come the back pressure in discharge side without substantial drop in the capacity. ln other word
when there is substantial drop in the pumping capacity while overcoming the pressure one say
that the pump is not developing enough pressure.

Starting : The pump is self priming & therefore the use of the foot-valve is not necessary For the
initial run the pump should be filled through suction branch ( if a negative suctron is there ) On
subsequent start-ups this measure is not necessary & the liquid remaining in the casing is

PREPARATION OF FOUNDATION
FOUNDATION
A good solid foundation is important securely bold
base plate units after leveling with shims for wedges.
Recheck with straight edge after tightening bolts. A
twisted base plate produces heavy stress on motor
& pump.
A shim or wedge should be close to each foundation

is checked. Then the wedges for shims may be
grouted to prevent loosening. Place pump in
accessible location to speed inspection and
maintenance. When pumping hazardous fluids, be
sure pump has good air circulation. Avoid pit

MAINTENANCE
Periodical
:
a) Alignment of the pump & motor should be checked.
b) suction line should be checked for no air leakage & jamming of the dust in filter
c) lf there is a pressure dropped, the relief valve should be further screwed in till desired pressure is
achieved. lf this does not give result then there should be a considerable wear in the wear plates,
which should be replaced.
d) Leakage, if any, on end covers eliminated by tightening bolts.
e) Mechanical Seal, if found leaking, check following.
1.
lf there are scratches on lapped faces of stationary seat or face housing due to foreign bodies,
scratched part should be replaced. While replacing the lapped faces must be thoroughly
cleaned.
2.
lf 'O' rings are busted, they should replaced, working smoothly, removed obstruction & make
it smooth
YEARLY
a) lf the pressure drop is too much the gears or the wear plate as the case may be, should be
changed due to excess wear on them.
b) On dismantling, if the body shows wear, then it should be sent back to us for replacement. This
will be in a very long run only.

IMPORTANT:
a) lf the pump gets jammed in running position, in that case loosen all the bolts on cover by half a
turn (this will be only in the case of pumps with bush bearings) & try to rotates then start the pump
& allow it to run smoothly & tighten the bolts slowly till there is no.jamming
b) lf the rotor does not rotate, then dismantling is necessary
c) Where the pump is excessively heated in the initial running & the jamming is caused, allow it to
cool down to the temperature till jamming is eliminated.

L.SBesign &Construction
SP200 & SP300 vacuum pumps are single stage, direct drive, oil-sealed & air cooled, A rotor with
three vanes is positioned inside the pump cylinder & it is supported by means of ty,,o bearings,
As the rotor rotates, the intake portion of the pumping chamber expands and sucks gas through
the inlet port. The gas passes through the open anti-suck back valve and enters the pump
chamber. As the rotor rotates further, the vane separates part of the pump chamber from the inlet
port. This part of the pump chamber is reduced, and the gas is compressed. At slightly above
atmospheric pressure, the gas is expelled from the chamber via the exhaust valve
This pumps comes with built in "Anti-suck back valve" and a metal wire mesh rough filtration for
protected in inlet. During standstill of the pump (for example due to shutting down or a po\ver
failure) the valve closes the intake. This prevents the pressure from rising in the connected
chamber while the pump is vented at the same time. Any suck-back of pumptil into the vacuum
system is thus also effectively prevented.
This vacuum pump has an inbuilt gas ballast valve with variable mode and easy accessibrlit,t; by
this feature the condensable gases or vapours can be removed depending on different applications.
SP200 &SP300 has one of the simplest & most reliable oil recirculating systems; the oil crrcrlation
in pump chamber for sealing, lubrication and cooling of the pump is recycled from the pump's oil
reservoir and additional features include automotive type spin-on oil filter which filtered the oil in
every cycle. The oil carried with the process gas is roughly separated in the oil reservoir before the
discharged gas enters the integrated exhaust mist filters where the fine oil mist is trapped, The
filtered oil is collected in the oil chamber and then supplied back to the pump through floai valr.re.
The pump rotor is made from medium carbon steel and the pump body is made out of h gh grade
cast iron. The oil tank and end covers are made from aluminium castings. Other mater als of
construction include fluorocarbon elastomers (FKM), chemically-resistant polymers etc, -the blades
are made from a specially selected high wear and corrosion resistant material.
The pump is directly driven by a three-phase electric motor through a flexible motor-couplrng, All
components including anti-suck back valve, exhaust mist filters, oil return line rvith float valve are
made extremely compact considering high efficiency of the pumps.
L.6 Gas-ballast control
Too pump high vapour loads, gas-ballast is delivered into the pump, by opening the gas ballast
valve; a controlled amount of air is admitted into the pump chamber. This gas ballasl prevents
condensation (up to the limit of water vapour tolerance specified in the Tethnical Data) rvhen
pumping condensable gases or vapours.

2.8 Electrical data for three-phase purnps
The motors are specific for the supply voltage and frequency. Do not attempt to use the motor
:
with either the rncorrect voltage or frequency.
The pump will start at a temperature down to 120C. At low temperatures the motor will draw the
start-up current shown in Table 6 for up to several seconds. The current will then reduce qurckly
as the motor reaches rated rotational speed. Within 5 minutes, as the oil and pump warms up, the
current drawn will slowly reduce to a maximum of the full load current specified in Table 6,
:
Electrical short-circuit and ground-fault protection of the pump will be provided by fitting Class
fuses of the values shown in Table 6 at the point of connection to the supply.
-
If these are not available in your country of use, type aM European fuses of the same ratrng can
also be used.

3.3 System design consideratioms
Consider the following points when you design your pumping system:
1.
Use a suitable valve to isolate the pump from your vacuum system if you need to allow the
pump to warm up before you pump condensable vapours or to provide additional system
protection when the pump is switched off.
2.
If continually evacuation of gases are not done its recommended to keep the pump running
and mount a suitable isolation valve with opening and closing into the inlet line and do not
switch off and on the pump repeatedly
J.
Avoid high levels of heat input to the pump from the process gases, otherwise the pump may
overheat and seizeand cause your external thermal overload device to open.
Z-S
pump may reach
,
temperature of more than 7OoC.
',,ri::J.1:,,.,,-
1f;$J
If you use the pump in a high ambient temperature and have a high gas throughput, the
ternperature of the pump-body may exceed 70oC and you must fit suitabie guards fitted to
prevent contact with hot surfaces.
4.
Make sure that the exhaust pipeline cannot become blocked.
5.
If an exhaust isolation valve is fitted ensure the pump cannot be operated with the valve is
cl osed.
6.
Provide for a purge of inert gas when you shut down the pumping system, to dilute dangerous
gases to safe concentrations.
3.4 Pump Handling & Location
The pump has a Lifting eye situated on the top of the pump; this should be used for lifting.
Alternatively you may use slings around the motor and the pump body to lift the pump.
CAUTION
Suitable lifting equipment should be used
Provide a firm, level platform for the pump. Locate the pump so that the oil level sight glass is
visible and the oil pouring plug, oil drain plug and gas-ballast control are accessible,
If your pump will be located inside an enclosure, make sure that there is adequate ventilation at
both ends of thepump, so that the ambient temperature around the pump does not exceed 40oC.
There must be a minimum space between the pump and the enclosure walls as described in Fig 4
and Fig 5,

Note:
To prevent automatic restart of the pump-motor if the electricat supply is restored after an electrical
supply failure, cannect the pump to the electrical supply through suitable control equipment which must
be reset manually after an electrical supply failure
We recommend that you connect the electrical supply to the motor through a starter or circuit breaker
which has thermal over current protection which can be adjusted to suit the full load current ratings
shown in Table 6. The fuse ratings in Table 6 are provided for guidance only. The supplier of your thermal
over-current protection device may specity different values to ensure correct operation of the fuse and .
the over-current protection device. Ensure that the fuse you use is suitable for the starting currents
given in Table 6.
i.
Pass the electrical supply cable through the cable-gland. The diameter of the electrical supply
cable should be in the range 7 to 11 mm - depending on motor rating.
2. Use insulated crimped connectors to connect the wires in the cable to the terminals in the
terminal-box as shown in concerned Figures. You must tighten the earth (ground) terminal
connection to a torque of 2.73 to 2.87 Nm.
3
Enslre that the cover gasket is correctly positioned, then refit the cover to the terminal-box

1, The pump inlet port has 2" G thread which can be connect using a Nozzle with a vacuum tight
flexible hose or pipe and also an adapter can be used to convert the inlet according to your
reouiiement.
2, The nominal dtameter of the pipe has to be at least the same as the diameter of the pump's
inlet flange. Restriction in pipes must be avoided in order to achieve the right pumping speed.
3. If necessary, incorporate flexible bellows in your system pipelines to reduce the transmission
of vibration and to prevent loading of coupling-joints. if you use flexible bellows, you must
ensure that you use bellows which have a maximum pressure rating which is greater than the
highest pressure that can be generated in your system. We recommend that you use HHV
Pumps flexible bellows.

:.tf tfie oil level is unusually low, check the oil float valve section 5.5.6.
5.3,1 Checking the oil condition
IRJARNING
Residual condensates dilute the oil, deteriorate its lubrication properties and
can cause a seizure of rotor.
fttgi Ihe oil should be light, either transparent, a little foamy or a little tarnished. A milky discolomtion that
dw not vanishes after sedation of the oil indicates contamination with foreign material. Oil that is either
contaminate with foreign material or burnt must be changed
ir c;-;e the oil appears to be contaminated with water or condensates despites proper use of gas ballast, clean
lhe -oas ballast filter with appropriate cleaning agent

Note: Refer to Fig. 1 for the item numbers in brackets.
1" Operate the pump to reach working temperature to warm the oil and then switch off the pump
(this lowers the viscosity of the oil and enables it to be drained from the pump more easily).
2. Pump while operateis hot and some pump-body surfaces could reach a temperature higher
than80oC and can cause burn by touching. Take note of warning labels on the pump and use
appropriate safety measures.
Isolate the pump from your electrical supply.
1. Remove oil pouring-plug (2).
5. Remove drain-plug(3)from oil reservoir & Radiatorto allow the oil to drain into the container.
6. When the flow of oil slows down, screw back the oil drain plug (3) and oil pouring-plug (2),
briefly switch on the pump for max 5 seconds and switch it off. Remove the oil drain plug (3)
and oil pouring-plug (2) again and drain the remaining oil.
3.
7.
5.4.1 Replacement of Oil filter
1.
2.
The oil filter is located at the rear side of the oil tank towards motor side of pump
Ensure the oil is drained from oil reservoir as describe in section 5.4 before replacing the oil
filter
Unscrew the oil filter and replace it with the new oil filter by moistening its sealing surface with
oil and screw it manually.
4. Plug the oil drain plug and unscrew the oil pouring plug and fill the pump with fresh oil up to
the bottom edge of the oil level sight-glass, run pump for a short time and then change the oil
3.
again, Use suitable oil as describe in section 2.6.
Depending on the process involved dangerous substances may escape from the pump and oil.
Take appropriate action
6. While disposing the filter, please follow the regional environmental regulations.
5.
5.4.2 Replacement of exhaust mist filters
1. Whenever you found there is oil mist coming out from exhaust and the pump is consuming
more oil or back pressure gauge is indicating more than 0.5barabsolute in oil reservoir, it signs
that the exhaust mist filter is clogged, HHV pumps exhaust mist filters are designed with
inbuilt bypass valve considering safety, when the exhaust filter element are clogged the
bypass valve opens and the filter is bypassed to avoid any accident or damage to pump.
2. The exhaust filters must be replaced more frequently if subjected to increased oil crack ng
products at high operatingtemperatures or aggressive media.
3. To replace the exhaust mist filter remove exhaust flange with O-ring by opening scre\./s on t
l-.
j,
lj
and then remove the clamps over the exhaust mist filters and you can replace it r,vtth ne,.^,,
exhaust mist filter with O-ring on it then reassemble.
While disposing the filter, please follow the regional environmental regulations.
Note: Du,-ing operation the exhaust mist filter get saturated with oil. It is therefore normal that tnar tn. ci'
tj
: .. .',',t be drop slightly after replacement of exhaust mist filters.
t'lj
tj
I
If the oil drained from the pump is contaminated, pour clean oil into the pouring-hole and
allow it to drain out of the pump. Repeat this step until the oil reservoir in the pump has been
thoroughly cleaned.
8. Refit the drain-plug (3).
9. Fill a suitable container with clean oil and pour the oil into the pouring hole until the oil-level
reaches maximum mark. (Refer section 5.3 for oil level check details).
10, While disposing the used oil, please follow the regional environmental regulations.

high speed rotation of approximately 3,000 R.P.M. The rotation of the lobes. clraws arr
frr}nr lne side oi the cylindrrcal housing and kaps it between the lobe and the housrng
Further rotation pushes th* trapped volume of air around the centre and discharges rt
from the outlet into the atmospheric pressure existing there. For every rotation lwjce
lhe volume is b*ing trapped by *ach lob* and expelled in a continuous flow.
Y
f
The Soots pump is a positive displacenrent type pump lts pumping capacity is
err:lroilerJ by physical dimensions, i.e.. operatir"rg speed af the pump, inlet and outlel
pressu.a cnnclrtions and the capacily cf the backing punlp. The Roots pLrmp should
n*v*r b* used directly wrthcul a backrng pump for evacuation. Pumps could get
*verlnarl*el and thereby get overheated, causing seizure of lobes and damage to the
plnrps. Hence, Roots pumps are not suitable as normal pressure blowers.
3"* IN$TALLATISN
a.
tJnpacking
Unpack the pump ancl remove, all pr*tective covers- Errsure lobes are cleaned of any
cust pal"lrcles by removing the inlet and outlet c*vers provided at the time of packing.
Th* punlps exterlnr should also be thoroughly clean*d *l arry clust before installing the
Roots p.rrnp on the hacking purnp line. Check for any possible transit damage and if
f*und a!right, proceed furiher.

LUBRICATION
Tha Roots purxp has three nrain lLrbricating points in it. The timing gears on the Roots
Vacuunr Pi-rmp are lubricated by gear teeth elipp*d int* the oil in a secondary oil pr"rrnp
instde the gear housing Splash from the gear iubricates both i:earings orr the shaft.
Th* oil flows ihrough an orifice hole,from the primary reservoir to tire secondary
chamber. Oil seals i:ehind th* bearing at both ends prevent oil from entering the
inlernal chamber. The marn shaft seal consists of two oil seals facing one another. The
reservoir of oil which is vented to atnrospheric pressure fiils the space betw*en tire tlvo
seals and lubncales the rubbing fares and also prevents any leakage from tire
atmospheric srcie into the pump side.
The rear and front end oil reservoirs are to be filled through openings at the top. Pour
oil r.,,iith use of a funnel into both resery*irs until level rises to the top of the oil sight

A prelininary no load candition operation of the pump is recommencled to verify the
ciireciion of rotatron, gears ancJ oil systenr functroning properly. lt also helps to verify

r"* $AFETY PffiECAUTIOruS
For safe operation and rnaintenance of the pump, the following points are to be strictly
adhered to:
i.
Do not reach for any rotating part of the pump or the motor while in operation
or while subject 1o accidental stading.

iii
Cover all exlernal moving parls wilh guards.
Disconnect powsr to motcr while changing the b*lt or datng any internal
cleanrng.
Alr,vays use pratective fuses and safety clevices like starlers and contractors
for the clrive motor.

A regular schedule of insp*ction and maintenance service is an effective methocl of
n:inimizing any repairs or failure of the pump. A simple record of services with dates is
rs*CIr"'nmended.
As discussed under lubriralinn, *orrect lubrication is CIne the nlcst irepartant
nequirements. other than operaiing the booster within its specified rated linrits. 1n a
new and properly installed unit, there are no contact points between the two impellers,
ar between the impellers and cylinder or head plates. Wear is then confin*ej to the

damage to casing and gears is likely to occur inrmediately after the bearing fails.

lnternal Clearances
Fcr a tlcoster in gocd operating condition, informqtion on the specific values of internal
clearances is of no real benefit. Situations may arise; however, rvhere it is desirable tr
compare existing clearances with the correcl engineering values. lt should be kept in
mind that clearances may change slightly in service, but they should never be less than
the mlnimum values. ln any case, only well qr"ralified and experienced personnel
shculd aitenrpt to n:easur* clearances for direct comparison.
