Product Description

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.
Pumping rate: 40, 71, 125, 180, 250, 300, 355, milliliter per rotation (A4VSO300 is special designed for ceramic press)
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
