Product Details

variable speed hydraulic pump

Various models good working condition variable speed hydraulic pump

Product Description

This product is 20 series hydraulic transmission system introduced form American company. It is closed hydraulic system made

up of axial hydraulic pump and motor. The pump is variable pump with charge pump and motor is fixed-displacement or

variable- displacement motor with valve assy. The control way of changing displacement includes MDC, HDC, and EDC which

can efficiently control discharge, direction and power of the output oil. The hydraulic transmission system made up of this series

of pump and motor has features of wide work range, reliable working state, easy operation and can be widely used on the

hydraulic apparatus of engineering machine, agricultural machine, mine machine, aviation and transport machine.
