Product details:

H-A4VSO variable piston pump can completely take the place of the German Rexroth pump.

The characteristics of the A4VSO pump: bevel disc structure, axial piston variable pump, which is specially designed for the high efficiency hydraulic drive with open loop.

◆Wildly applied for ceramic press, refractory press, steel, forging and pressing, metallurgy machinery, mine machinery, ship machinery, petroleum equipments, engineering and machine tool control.

◆Angle indicator with bevel disc

◆Excellent sucking characteristic

◆Sensitive response control

◆The special designed long life and the high precision aviation roller bearing

◆Lower noise, long life, better power and weight proportion 

◆Connected shaft structure, and combine a pump by piling up.

◆The flux of the hydraulic pump is in proportion to the rotating speed and pumping rate. The pumping rate is adjustable through bevel disc angle.

◆Complete control mode, including DR/DRG constant pressure control, LR hyperbola constant power auto-control, and EO2 electrical proportional control.

◆Rated working pressure up to 350Bar(35MPa)

◆Suitable media: mineral oil and water glycol. The clearness grade: above NAS9

◆Deliver time: one mouth. The series A4VSO125, 180, 250, 355 is ready at any time
