Product Description

Rexroth A4vg Series A4vg28 A4vg40 A4vg45 A4vg56 A4vg71 A4vg90 A4vg125 A4vg140 A4vg180 A4vg250 Hydraulic Piston Pump

Nominal pressure 400 bar
Peak pressure 450
Control device: NV, HD3, HW, DG, DA1, DA2, EP3, EP4, EZ1, EZ2         

Control mode:
NV type, no control device
DG- hydraulic control, direct control type
Ez-electrical two-point control with switching electromagnet
Hd-hydraulic control, related to pilot pressure
HW- hydraulic control, mechanical servo
EP- electrical control with proportional electromagnet
DA- hydraulic control, related to deceleration
 

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
