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
