Variable Displacement Piston pump A11VO for Crane &Drilling Machine, China Variable Displacement Piston pump A11VO for Crane &Drilling Machine Manufacturers, Suppliers, Factory - Wenzhou Prance Hydraulic Equipment Co., Ltd

Feature:

1.Variable displacement pump with axial piston drive swashplate design for hydrostatic drives in open circuits

2.Design primarily for use in mobile applications

3.Pump operation either self-priming,with tank charging or charging pump

4.A comprehensive range of varialble units is available for different control functions

5.Power can be adjusted from the outside , even when the machine is running

6.The through drive is suitable for attachment of gear pumps and axial piston pumps up to the same size , i.e.100% through drive

7.The Volume flow is adjustable in proportion to the dirve speed and displacement and is infinitely variable from QVmax to QvMin=0
