Water Injection Pump for Coal Mine
- Max. pressure: 31.5 MPa
- Max. flow: 125 L/min
Juneng’s BZW series water injection pump is designed to convey water, emulsions, and chemical liquids with properties similar to water. It is suitable for departments requiring high-pressure liquid equipment and are widely used in the coal mining industry.
This pump is especially suitable for applications requiring mobile operation and serves as a reliable power unit for high-pressure water jet equipment. Extended versions of the series can also be used to convey slurry, cement slurry, and other liquids with a certain viscosity.
At the pump head, one end is equipped with an overflow valve, while the other end is fitted with a throttle valve or pressure gauge and a high-pressure hose connector. This configuration enables adjustment of the system working pressure while preventing the pump from exceeding its rated pressure. The pump features safe and reliable operation, a self-circulation system, and ease of use.
