Reciprocating 850/2 Mud Pump for Drilling Operations
The BW850/2 mud pump is a horizontal reciprocating double-cylinder double-acting piston pump, specifically engineered for geological drilling in depths ranging from 200 to 500 meters. This high-pressure stable mud pump efficiently transports mud, clean water, and other flushing fluids, making it ideal for hydrological water wells, core drilling, and various drilling applications.

Performance Characteristics
- Pressure and Displacement: Positive displacement supercharging design generates high pressure of 2.0-3.0 MPa for deep drilling requirements. Dual-cylinder double-acting structure provides stable displacement (850/600 L/min) suitable for high-concentration mud transportation.
- Media Adaptability: Handles mud with sand content up to 10% using one-way control valves and leak-proof seals. Requires strict medium filtration to prevent valve blockage from impurities.
- Speed Regulation: Displacement adjustment through variable speed mechanism by changing piston stroke frequency. Provides stable speed regulation with gear shifting during operation stops.
- Wear and Maintenance: Reciprocating friction between piston and cylinder liner requires regular replacement of vulnerable parts and consistent lubrication maintenance to maintain sealing performance and lifespan.
- Startup and Load: Requires water injection and exhaust before startup to form sealed pump chamber for negative pressure water suction. Features smooth clutch engagement to manage high startup loads and prevent power shock.
