Adopting area
BRW400/31.5 type emulsion pump can be used as a high-pressure and big-flow pump station, mainly used in providing power resource for the high yielding working face whose output is over one million per year, it can also be used in providing power resource for the ground hydraulic devices, this type of pump station usually is composed by one tank and pump.
Structure feature
*The horizontal five-plunger has small flow pulsation.
*The fourth grade engine drive (200Kw) with large power, the first grade cylindrical gear of speed cut. High shaft speed, small volume and light weight.
*New unloading valve with large flow. The road can exactly let the whole flow go through. It has completely interchangeability with unloading valve of BRW315/31.5 pump.
*The double cooling lubrication has low oil temperature and reliable lubrication.
*The five independent pump heads are convenient for maintenance.
*The liquid box can stop the engine automatically if there’s low liquid level.
*It has strong generality with BRW315/31.5 pump station.
