IFP PVB PISTON PUMP PERFORMANCE CURVES
MODEL PVB5BASED ON OIL TEMPERATURE OF 120° F (100 SUS)1800 RPM INPUT-ATMOSPHERIC INLET
SHAFT ALIGNMENTPVB units are designed for "inline drive" with a flexible coupling. Side loading the shaft is not recommended .
FILL PUMP CASINGBefore starting, fill case with system fluid through upper most drain port. Pipework must be installed in such a way as to ensure that the case is always full of oil during operation.
Note: -Max. case pressure 5 PSI.
STARTINGDuring initial starting it may be necessary to bleed air from pump outlet. IFP air bleed valve ABT 02S is available for this purpose.
SYSTEM RELIEF VALVEAlthough PVB series pumps have compensator controls, a system relief valve is recommanded for safety considerations.
TECHNICAL DATAValues based on using anti-wear type petroleum oil 150 SUS at 100° F and 0 PSI inlet pressure
Load sensing comp. controlport .4375-20 UNF-2Bconnected to downstreampressure
(942159N)/(942158N)
- Pressure compensator- "C" control maintains pump volume requirements of the system until a preselected operating pressure is reached. Pump displacement is then reduced to zero"CM" range 250 - 1500 PSI"C" range 250 - 3000 PSI
Available in frame sizes PVB5 to PVB45
(942480N)- Remote pressure compensator- "CG" control operates same as "C" control except pressure setting can be adjusted using a remote relief valve (IFP-C175-*-70) connected to the remote control port (SEE Page I1.1-I1.2).
Available in frame sizes PVB5 to PVB29
Available in frame sizes PVB5 to PVB29
924069N)- Load sensing/pressure limiter- "CVP" compensator provides load sensing control to automatically adjust pump flow in response to a remote pressure signal. A compensator control is also incorporated to limit maximum working pressure.
OPTIONAL CONTROLS
(C.W- decrease)(C.C.W.- increase)
Maximum volume stop incorporates the "C" compensator with an djustable volume stop. The maximum pump delivery is externally adjusted.
-Level control- "M" control provides manual adjustment of pump flow. Level must be secured in position to maintain prespected flow.
-Handwhell control- Turning handwheel provides over- center control of pump output flow.

C*V - LOAD SENSING ANDPRESSURE COMPENSATED
C*V pressure control provides powermatching of the pump pressure andoutput flow to the systems loaddemand. Load sensing ensures thepump always provides only the amountof flow required by the load. The pumpoperating pressure adjusts to theactual load pressure demand plus apressure differential required for thecontrol action. If the load pressureexceeds the system pressure setting,the pressure compensator de-strokesthe pump. When system is notdemanding power, the load sensecontrol will operate in an energy savingstand-by mode.
Note:PVH thru-drive pumps have an SAE-A pad mountSAE- B & SAE-C pad mounts require a flangeadapter to be mounted to the SAE-A pad of thePVH thru-drive pump
