The BZW400/10 water injection pump can serve as a high-pressure hydraulic power source. It is suitable for conveying water, emulsions, and other water-based chemical liquids. This pump is widely used in coal mining applications that require high-pressure liquid equipment. Both the suction and discharge ends of the pump are equipped with safety valves, throttle valves, and a self-circulation system, allowing flow adjustment to meet different operating requirements. The power end adopts a shaft-type transmission structure connecting the crankshaft and connecting rod and uses splash lubrication, enabling continuous 24-hour operation without the need for cooling.
Applicable standards for water injection pumps:
- MT/T 188.2-2000 Coal Mine Emulsion Pump Station – Emulsion Pump
- Q/JN001—2022 BZW Series Water Injection Pump
