Adopting area
The BRW315/31.5 type five prop pump is based on the common crankcase, and it drives new pumps with its own pressure date. With RX400/25 emulsion tank ,it can be used to provide power source to the both underground mining devices and ground hydraulic devices.
This pump station is usually made up with two pumps and one tank.
Structure features
*The horizontal three-plunger has small flow pulsation and stable operation.
*The fourth grade engine drive (315Kw) 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.
*The double cooling lubrication has low oil temperature and reliable lubrication.
*The five independent pump heads are convenient for maintenance.
*The liquid box can make emulsion liquid, keep the liquid level and stop the engine automatically if there’s low liquid level.
