LPV130 Axial Piston Hydraulic Oil Pumps High Pressure Hydraulic Pump

Product Description

 Highland LPV130 axial piston hydraulic oil pumps with high working pressure

Highland LPV130 hydraulic oil pumps basic information: 

Highland Hydraulic oil pumps are piston or piston reciprocating direction parallel to the cylinder center axis of the Piston pump. Highland hydraulic oil 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.
