A4vg250 Rexroth Axial Piston Variable High Pressure Hydraulic Pump

A4vg28/A4vg45/A4vg50/A4vg56/A4vg71/A4vg125/A4vg180/A4vg250 Rexroth Axial Piston Variable High Pressure Hydraulic Pump

Features:


1.type axial plunger variable pump for closed circuit hydrostatic drive
2.The flow rate is proportional to the driving speed and displacement and can be variable without grade
3.The flow rate increases from zero to its maximum with the Angle of inclined disk
4.The flow direction of the liquid flow can be changed smoothly by making the inclined disk swing through the middle position
5.Various variable modes that are easy to match with various control and regulation systems
6.The inlet pump is equipped with two overflow valves on the high-pressure oil side to protect the static hydraulic drive (pump and motor) from overload
7.The high-pressure overflow valve of the inlet also has the function of filling oil valve
8.The internal auxiliary pump is used as the refill pump and control pump
9.The maximum oil refill pressure is limited by a built-in oil refill overflow valve
10.Full series with built-in pressure shutoff valves
11.Nominal pressure 400 bar,Peak pressure 450
