Single acting electric oil pump for cylinder jack is made of electric motor, low pressure oil pump, high pressure oil pump and oil box. Small dimension, high pressure, light weight, simple structure, and it has a spare joint for connecting oil gauge. 
If the single acting electric oil pump is matched with other hydraulic tools, it can supply driven for lifting, profiling, bending pipe, straightening, tearing down, cutting, installing, gauging pipe, punching and etc. It can reduce labor strength and increase working efficiency.
Single acting electric oil pump for cylinder jack is single outlet, high-low pressure pump, parallel type hydraulic power pack, high-low pressure pump supply oil at the same time when low pressure, it can get the large output flow; low pressure pump automatically unloading back the oil via control valve when high pressure, it can reduce the consumption of electric motor and heat of oil, it has the function of stop machine to protect pressure, single oil-way backing oil and etc.

1) Single acting electric oil pump for cylinder jack is matched with other hydraulic tools, it can supply driven for lifting, profiling, bending pipe, straightening, tearing down, cutting, installing, gauging pipe, punching and etc.
2) Single acting electric oil pump for cylinder jack  also can be installed into some machines for supplying power packs. 
3) Single acting electric oil pump for cylinder jack as a test pressure pump station for kinds of high pressure hydraulic components, high pressure container, high pressure rubber hose.
 

1) Single acting electric oil pump for cylinder jack small dimension, light weight, convenient usage, high working pressure.
2) Single stage pump station: simple structure, it can get higher working pressure. 
3) Double stage pump station: high-low pressure pump supply oil at the same time when low pressure, it can get the large output flow; low pressure pump automatically unloading back the oil via control valve when high pressure, it can reduce the consumption of electric motor. 
4) Holding function: at the condition that outer oil-way is no reveal, stop the pump for holding 5 minters, rated pressure reduce less than 5Mpa.
