Product Details

Construction machinery PV21 hydraulic pump exported to world

Product Description

Application Range:

This product is hydraulic transmission system introduced form American . It is closed hydraulic

system made up of axial hydraulic pump and motor. The pump is variable pump with charge pump and the motor is fixed-

displacement or variable-displacement motor with valve assy. The control way of changing displacement includes MDC, HDC and

EDC which can efficiently control the discharge, direction and power of the output oil. The hydraulic transmission system made up

of this series of pump and motor has features of wide work range, reliable working state, easy operation and can be widely used on

the hydraulic apparatus of engineering machine, agricultural machine, mine machine, aviation and transport machine.

Hydraulic Pump of PV20 Axial Piston Variable Displacement Pump Fetures:

1. Series 20 Axial Piston Variable Displacement Pumps are well engineered and easy to handle.

2. The full-length shaft with a highly efficient tapered roller bearing arrangement offers a high loading capacity for external radical forces.

3. The pumps can be connected with other additional pumps.

4. The hydro-mechanical servo displacement control maintains the selected swash plate position and hence pumps displacement.

5. Upon release of the control handle, the swash plate automatically returns to zero position and the flow reduces to zero.

6. High case pressures can be achieved without leakage even at the lowest temperatures by using suitable shaft seals.

7. The servo valve arrangement offers the facility to incorporate function regulators and remote control systems.

8.Axial piston units are designed for easy servicing. Complete dismantling and reassembly can be carried out with standard hand

tools, and all components or sub-assemblies are replaceable.
