LPV110 Axial Piston Pump With 95% High Efficiency Is Suitable For Walking Mechanical Equipment

Product Description

 Highland LPV110 aviation industry axial piston pumps lifetime technical support

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 Axial piston pumps main features: 

Optimized design: Compactness appearance make operating your machine as simple as possible,

still providing best quality at highest standards.

Clean and flexibility: The lightweight, compact design. Precise control and reliable quality and performance.

Wide range of displacements: Offering a range of pumps with 30-130 cm² per round.

High pressure capability: Working with 420 bar transient pressure.
