Durable Structure Mud Pump Fast Flow Adjustable Pressure
The BW250 mud pump is a horizontal triplex single-acting reciprocating piston pump, serving as essential equipment for drilling operations. It efficiently circulates mud water under pressure to bring rock clastics to the surface, cool drill bits, lubricate tools, and protect well walls, directly impacting drilling efficiency and operational safety.

Working Principle
The mud pump is a horizontal triplex single-acting reciprocating piston pump.
During operation, the crankshaft drives the piston to move back and forth in the cylinder.
When the piston moves backward, a negative pressure is formed, and the liquid is sucked into the cylinder.
- When the piston moves forward, high pressure is generated to discharge the liquid.
- The three cylinders work alternately to realize continuous and stable high-pressure fluid delivery for drilling flushing and grouting.
- Geological Exploration: Core drilling (up to 1500m with diamond bits, 1000m with hard alloy), mineral exploration, and geological structure analysis.
- Construction Engineering: Foundation reinforcement for high-rises/bridges, tunnel wall grouting, and cast-in-place pile construction.
- Mining Operations: Mine drainage, tailings slurry transportation, and maintaining safe working environments.
- Hydropower Projects: Dam anti-seepage treatment, channel lining, and infrastructure reinforcement.
Core role (drilling rig matching)
Send the mud to the bottom of the hole to cool the drill bit
Bring rock debris and sediment back to the ground
Form a wellbore protection wall to prevent hole collapse
Can be used for high-pressure grouting, leak sealing, and reinforcement in engineering
