VQ High Pressure Single Vane Pump

Our company is one of the professional High Pressure Hydraulic Vane Pump manufacturers & suppliers in China

Introductions:

VQ High Pressure Vane Pump is designed for engineering machinery development of high-performance lash high-pressure pump,suitable for construction machinery,especially for walking machines.

Features:

1,Hdraulic balance of the dual blade structure design,high pressure,up to 21Mpa,

2,Floating side panel structure,can compensate gap automatically.To achieve pressure balance,achieve superior performance of high speed and high pressure.

3,Side plate of vane pump uses double metal flexible materials,to improve anti-seizure properties greatly,and make the pump high efficiency and long lifetime.
