Adopting area
The BRW125/31.5A is based on the common crankcase QZX110, which later derives the according flow, pressure date and it can be made up to a emulsion station. It provides hydraulic power to the mining devices, also can be used to clean the ground hydraulic device.
The pump station usually is composed by two pumps and one tank, the pumps can be used both separately and together.
The structure features
*Horizontal three-plungers, cone shape suction and drainage valve.
*Quadruple explosion proof motor drive, rubber type coupling element, first grade cylindrical gear reduction.
*It is equipped with energy accumulator (25L), safety valve and unloading valve.
*The pump head can’t unload while change the plunger seal.
