A4vso250hs4/22l-vpb13noo Rexroth A4vso Hydraulic Piston Pump Variable Displacement Excavator

Hydraulic pump features ：

1) The flow rate of the pump is proportional to the speed and displacement of the pump, and the swashplate angle of the pump can be adjusted to adjust the displacement steplessly.

2) Coaxial structure, can form a combined pump

3) Position constrained backhaul structure

4) Spherical flow distribution, the plunger is arranged obliquely around the main shaft

5) Stepless variables

6) Excellent inhalation capacity

7) Control time is short

8) Low noise

9) Long life

10) Excellent power/weight ratio

11) Modular design

Rexroth oil pumps cover road rollers, pavers, pavement heaters, and road machinery in pavement machinery applications.

How to achieve adjustment ：

1) Swash plate type axial piston variable pump for open hydraulic rotary circuit

2) Mainly used in the field of mobile machinery

3) The pump works under self-priming conditions, the mailbox is pressurized or with a built-in suction pump, (centrifugal pump)

4) The output flow is proportional to the drive speed and can be steplessly varied between the maximum and zero values.

5) Multiple controls to meet different operational requirements

6) Adjust the power control externally even when the pump is running

7) Pump series piston pump with coaxial drive, can be connected with gear pump and axial piston pump up to the same specification to achieve through-shaft drive

8) REXROTH hydraulic pump high power characteristics

High pressure, quiet technology, low dispatch, smooth running, radial and plunger compensation, high power, superior suction, wide range of operating oil, flow range from 0.35CC-500CC, multi-connected.
