Pump is driven by air and produces high hydraulic pressure.

Pressure is adjusted by an air-adjusting valve. When pressure reachesmultiples of super charge, the air valve will stop operation.

Hydraulic pressure will maintain for a long time even when there is apower failure or the air pressure disappears.

Long-time hydraulic pressure lastin allows less power consumption;safe, economical andconvenient.

Measurement: L470 x W 180 x H 350(mm).

With pressure on-and-off sensing functions.
