Variable Displacement Vane PumpsVVA 10/20/40, 20 series and VVA 80, 10 series single and multiple pumps

Basic CharacteristicsTypes Single and multiple pumps. . . . . .

(Multiples can include fixeddisplacement sections)

Displacement(variable sections) 10 to 83 cm3/r. . . . . . Speed range 800 to 1800 r/min. . . . . . . . Max. operating pressure up to 100 bar. .

General DescriptionVVA pumps are pressure compensatedvariable displacement vane pumpshaving separate adjustments for pressurecompensation and maximumdisplacement. Pressure compensatoroptions include single and dual adjustablepressure designs.

Modular design enables the user to buildmultiple pumps (max. of three pumpsections) quickly from individual pumpsections and adaptor kits containing allthe necessary parts. Multiple pumps cancontain pump sections of the VVA typeonly or a mix of VVA and Vickers vanepumps.

– High pressure settingWith pump outlet pressure applied atcompensator pilot port, turn locknut#2 anticlockwise to increase, orclockwise to decrease pressuresetting.

Caution – This setting must notexceed the maximum for theappropriate range as listed underin the ‘Model Code’ section.
