Chinese hydraulic piston pump is the part of hydraulic system of aluminium extrusion press. 

A7 series hydraulic piston pump is used for transforming the mechanical energy to hydraulic energy.

The feature of Chinese hydraulic piston pump: strong antipollution ability, simple structure, low noisy, low oil temperature, stable flow and pressure, high efficiency and durable. It is applied to the open type loop hydrostatic transmission. The flow, rotation speed in proportion to the displacement; it can achieve Stepless variable in the constant speed. It is good for aluminum extrusion press to produce various kinds of small and very thin and other special aluminium profiles with stable performance, constant speed and constant pressure.
