Product Description

The A7VO- series bent -axis hydraulic pump are made

in china with higher quality and competitive cost.

This A7VO series variable pumps’ function and the overall size along with

all of the spare parts are as the same as the Original A7VO series pumps

It can replace original A7VO series pumps very well.

The Variable motors A7VO series used for:

The Implement hydraulics of Construction Machinery: Mining excavators,Compact excavators, Concrete pumps, and so on...

CHARACTERISTICS of Rexroth A7V hydraulic pump:

1.Variable displacement pump,axial piston, bent axis design, for hydrostatic transmission in open circuits.

2.The flow is proportional to the drive speed and the displacement, the displacement is steplessly variable at constant drive speed.

3.High performance rotary group with well-proven spherical control area offering the following advantage: self-centering, low peripheral speed, high efficiency.

4.Drive shaft will support radial loads.

5.Low noise level, long service life.
