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. HY 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.

Values based on using anti-wear type petroleum oil 150 SUS at 100° F and 0 PSI inlet pressure
