3.6 How to Select and Size:
Select the pump size according to the capacity requirement of the application from the
inlet, back pressure and filling head conditions given in the table below.
Back pressure (h) = [H X 0.1 bar g] + FP bar g + LP bar g
where H=height to which condensate is to be lifted in mtrs.
FP= Frictional pressure drop of discharge

3.10Example:
Condensate load 1600 kg/hr.
Steam/air pressure available for operating pump 5.0 bar g
Vertical lift from pump to return piping 9 m
Pressure in return piping (piping friction negligible) 1.72 bar g
Filling head on pump 0.3048 mtrs.
Solution:
1 Calculate “h”, the total lift or back pressure against
which the condensate must be pumped.
= (9mx 0.1) + 1.72 = 2.62 bar g
2 From capacity table with 5.0 bar g operating inlet pressure
and 3.0 bar g back pressure choose a DN 40 pump which has a capacity of 2290 kg/hr.

4. Product WorkingPrinciple:
Note:ForthissectionrefertoFigure4
A PPPPU unit consists of a receiver (1), Inlet Isolation valve (2), Strainer (3), a body shell (4)
containing a float mechanism which operates a set of motive steam / air inlet (5) and exhaust
valves (6) and inlet (7) & outlet (8) disc check valves. The steam or air is used as motive media to
operate the pump. Condensate comes into the pump receiver (1) from flash vessel or plant
condensate header and is allowed to flow in to the pump body (4) having float mechanism by
openingtheinletisolationvalve(2).
Figure 4: Pressure Powered Pump Package Unit
Note:ForthissectionrefertoFigure3
In the normal position before startup the float is at the lowest position with the motive steam/air
valve(5)closedandtheexhaustvalve(9A)open.Whencondensateflowsbygravitythroughinlet

Asthefloat(16) continuestorise,themechanismlink(17) isengaged which increasestensionin
the springs (19). When the float (16) has risen to its upper tripping position, the linkage
mechanism (17) snaps upward over center. The energy in the springs (19) is released as the push
rod (18) is moved upward, to simultaneously open the motive steam inlet valve (5) and close the
exhaust valve (9A). Steam flow through the inlet valve (5) increases the pressure within the body
and closes the inlet check valve. When the pressure in the body shell (15) exceeds the
backpressure inthecondensate dischargeline,itopenstheoutletcheck valve(21)and forcesout
thecondensateinthedischargeline.
Asthecondensatelevelinthe pump body (15) falls,thefloat(16) islowered and mechanism link
(17) is engaged, which again increases the tension in the springs (19). When the float (16)
reaches the lower tripping position, the linkage mechanism (17) snaps downward over center.
The energy in the springs (19) is released as the push rod (18) is moved downward, to
simultaneouslyopentheexhaustvalve(9A)andclosethesteaminletvalve(5).Steam/airutilized
for pumping the condensate gets released through the exhaust valve and this completes one
pumpingstroke.
When the pressure in the pump body (15) has fallen to the same level as the pressure in the inlet
pipe, the inlet check valve opens. Condensate will again flow through the check valve to fill the
bodyandbeginnextcycle.

5. InstallationGuidelines:
Note: Before implementing any installations observe the 'Important Safety notes” in
section 2. Referring to the Installation and Maintenance Instructions, name-plate and
Technical Information Sheet, check that the product is suitable for the intended
installation.
Note:ForthissectionrefertoFigure5
1. Ensurethatthereisnodamageintransit.Beforeinstallationisdoneensurethatallsteam,air
or gas lines are closed. Select correct pipeline sizes as per the pump and connections are
available.Leveltheunitbylevelbottle.
2. The reservoir has 3 ports, two of them should be connected for condensate inlet (A) and
thirdis usedforventline©. Most importantisthatreservoirmustbevented to atmosphere.
Thisistoensurefreeflowofcondensateundergravitytothepump.
3. ItisrecommendedtoinstallPPPPUalongwithaForbesMarshallFlashvesselarrangement,if
condensateflashingisexpectedwhenexposedtoatmosphere.
4. Connect the condensate line coming from plant to the flash vessel inlet port. Install strainer
(1), single orifice float trap (2) and view glass (3) after the flash vessel and connect
condensateoutletlinetothepumpreceiver(6). Installthesafetyreliefvalve(4)andpressure
gauge(5)atrespectivelocationsprovidedon theflashvessel.Ensurethatthepump receiver
inlet is at a lower level than the condensate outlet line of flash vessel so the condensate
travelsbygravitytothepumpreceiver.
5. Ventline(C)shouldbepiped,unrestrictedtosafelocationintheatmosphere.
6. Connectthemotivesteamorcompressedairline(7)tothemotivesupplyinlet.
7. A pressure gauge (8) is supplied loose along with the pump. Install the same on motive line
syphon. Condensate discharge line (B) of pump should be routed to the boiler feed water
tankandconnectthesametothecondensatenozzleofde-aeratorhead.

5.1 Caretobetakenwhileroutingthecondensatepumpdischargeline:(RefertoFig.6)
1. The outlet line size should be equal to or more than pump outlet flange size provided
withpump.
2. As far as possible, the discharge line should have minimum bends. Ideally the
condensate pump discharge line should be lifted immediately after the pump to the
maximum elevation in the circuit and then to be connected to feed water tank with a
downwardslope.Thisensuresminimumbackpressureonthepump.
Figure 6 : Routing the condensate line to the Feed Water Tank
5.2 In case more than one condensate pump is connected to a common Condensate
line:(RefertoFigure7)
1. Make sure that NRV supplied with pump is installed with flow direction towards FWT.
TheNRVsizeshouldbeequaltothepumpoutletlinesize.
2. If more than one-pump discharge lines are to be connected to a common condensate
line, please ensure that the individual line is connected from the top with a non-return
valve. The common condensate line should be sized to take care of connected
condensateloadofallthepumps.

6. StartupandCommissioning:
It is recommended to install Forbes Marshall PPPPU along with a Flash vessel arrangement, if
condensate flashing is expected when exposed to atmosphere. For trouble free operation of
PPPPU,itis importantthatthesingle orificefloattrap internals,pump internals& checkvalvesare
notsubjectedtodirtorotherhardparticles.
Therefore, prior to bringing the PPPPU in to operation, please ensure that the entire condensate
pipingcircuitisthoroughlyflushed.

2. Once flushing of condensate and motive line is completed, open the motive line
isolation valve (6) and ensure that the motive media pressure should not exceed as
