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.

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.
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
