hydraulic cylinder with hydraulic pump

hydraulic cylinder with hydraulic pump

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.
