Description

Property

A7V Variable Pump

Products specification

Inclined shaft axial piston pump for open circuit hydrostatic transmission.The flow rate is proportional to the drive speed and displacement, and can be changed steplessly at a constant drive speed.The control range is complete and is used for every control and regulation function. It works with mineral oil and fire resistant liquids.

Structure features

Structure 1:High-performance rotary components and spherical hydraulic oil pan for automatic centering, low cycle speed and high efficiency

Having novel high-performance rotary components with improved technical data and spherical hydraulic oil pan with test,compact construction.

Technical parameters

Working pressure of inlet port

Absolute pressure of inlet port:Pabs min—0.08 MPa Pabs max—0.2MPa

Viscosity：Vmin——10mm2/s Vmax——（short time）1000mm2/s

Optimum working viscoity：Vopt——16~36mm2/s

Working pressure range of outlet

Rated pressure: nominal pressurePN—35MPa Maximum pressure PMax—40MPa

Temperature range T：-25℃~+80℃

The maximum allowable pressure of the drain port: the highest comparable to the inlet port pressure is 0.5 bar, but not higher than the absolute pressure of 2 bar.
