Configuration

Parameters

·Spray moulding coating, corrosion resistance, strong anti-pollution ability

·Portable and compact design,light-weight machine, convenient for move and transport

·Durable design, adapt to abominable working condition

·Design of double speed pump station,low pressure and big flow, execute component can move very fast under no-load condition, built-in high precision high and low pressure automatic switching valve

·External adjustable pressure valve,convenient for recalibrate working pressure, can prevent pressure overload

·Standard configuration of most model include motor starter, which has overload/overheating and electric leakage protection function

·Durable reversing valve, applied to single/double acting jack; choose magnetic reversing valve can realize remote control operation, and also can choose matched pump station

Single and double stage pump

Single stage pump station is suitable for the occasions with the following requirements: which has constant flow output in short time under certain or rated pressure. Such as working together with cylinder which has small tonnage or large tonnage, short stroke.

Double stage pump station has very big flow under each class(100 bar) pressure, and the maximum flow can reach 10 times of rated flow, this make the large tonnage and long stroke cylinder got fast plunger moving speed, and shorten a execution cycle obviously, and improve efficiency.
