4VN Series Pneumatic Pump

4VN Series Pneumatic Pump

4VN for special pump, hydraulic wrench assembly integrated way: by the oil pump, control valve, fuel tanks, pneumatic motor, cooler, such as instrument of a kind of independent complete hydraulic device, has small volume, light weight, simple structure, operating the French version, all kinds of high pressure, etc. Pump for high, bottom pressure oil pump simultaneously supply, can obtain the larger output oil quantity. When high pressure, the offset pump is automatically empty back to oil by unloading overflow valve and can reduce the power consumption, and (A) the oil pressure can be adjusted by 70~ 700bar.
