Air Powered Hydraulic Power Unit with Accumulator

The air powered hydraulic power unit is a high pressure hydraulic pump station. It is ready to connect, and can provide a stable hydraulic source for diverse hydraulic tools or occasions requiring hydraulic pressure.
The air operated hydraulic power station takes plant air or compressed air as drive power. And it can pressurize liquid to generate hydraulic power maximal 408MPa for hydraulic tools such as bolt tensioners, hydraulic clamps, hydraulic tube expanders, hydraulic actuators.
A hydraulic accumulator can be added to the hydraulic power unit. And the accumulator can effectively eliminate pressure peak in hydraulic circuit, thus ensuring stable pressure in hydraulic system.

The outlet pressure of the hydraulic power unit is proportional to driving air pressure. By adjusting the driving air pressure, the hydraulic power system outlet pressure can be adjusted accordingly. By controlling the driving air supply, the hydraulic power system working frequency can be controlled, thereby controlling the hydraulic flow. Just need to preset an outlet pressure, the hydraulic power unit will output hydraulic power. And it will automatically stop and stand by without energy consumption when reaching the preset pressure. In case of circuit pressure dropped, the hydraulic power system will automatically restart to replenish hydraulic flow.

Air Operated Hydraulic Power Unit Benefits

Compared with the Electric hydraulic power unit, the air driven hydraulic power unit has the following advantages:

  • Safe and explosion-proof. The pneumatic hydraulic power station is driven by compressed air, electric power is not required, avoid the risk of electric sparks, especially suitable for hazardous area.
  • Energy saving. When your preset pressure is reached, the inbuilt hydraulic pump will stop automatically and maintain the pressure without energy consumption. If the hydraulic system pressure dropped, the hydraulic pump will automatically restart for pressure compensation.
  • Low heat generation. The air driven HPU can maintain pressure for a long time, and the hydraulic fluid will not overheat during pressurization process and pressure maintenance period. Beyond that, the loss of hydraulic oil is tinny, and the service life is longer.

Customized High Pressure Power Unit

We provide multiple proven configurations of high pressure hydraulic power unit which are based on different hydraulic pumps and can output different hydraulic pressures and flows. In addition, we provide customized hydraulic power system.
