The pump station is composed of a pump device, a manifold or valve combination, an oil tank, and an electrical box. The function of each component is the same as that of the hydraulic station, as follows:

Pump device - equipped with a motor and an oil pump, it is the power source of the hydraulic station, converting mechanical energy into the power energy of hydraulic oil.

Manifold - It is composed of hydraulic valve and channel body. It adjusts the direction, pressure and flow of hydraulic oil.

Valve combination - the plate valve is installed on the vertical plate, and the pipe is connected behind the plate, which has the same function as the integrated block.

The oil tank is a semi-closed container welded by steel plates, and it is also equipped with an oil filter, an air filter, etc., which is used for oil storage, oil cooling and filtration.
