LPV110 Variable Displacement Axial Piston Pump Cast Iron

Product Description

 Highland LPV110 Factory Direct Sale Variable Displacement Axial Piston Pump

Highland LPV110 axial piston pumps basic information: 

Highland Axial Piston pumps are piston or piston reciprocating direction parallel to the cylinder center axis of the Piston pump. Highland axial piston pump uses the volume change produced by the reciprocating movement of the plunger in the plunger hole parallel to the drive shaft to work. Because the plunger and plunger hole are round parts, high precision can be achieved, so the volume efficiency is high.

Highland Variable displacement axial piston pumps main features: 

1. Have swash plate structure for reliable operation and a longer life.

2. Be suitable for hydrostatic transmissions with closed-loop circuit.

3. Manual servo and hydraulic variable control.

4. Variable displacement swash plate piston pumps with a charging oil pump.
