During operation, mud pump pistons reciprocate within cylinders, driven by the crankshaft or crosshead mechanism of the pump. As the piston moves backward, it creates suction that draws in drilling fluid into the cylinder. Upon forward movement, the piston pressurizes the fluid, forcing it through discharge valves into the drill string and borehole. This continuous circulation of drilling fluid helps cool the drill bit, remove cuttings, and maintain wellbore stability.
Our company strictly controls the production of mud pump piston assembly within the tolerance range, ensuring easy installation, wear resistance, corrosion resistance, long service life, and suitability for various harsh working environments.

Despite their robust construction, mud pump pistons are subject to wear and potential issues over time, including:
- Seal Wear: Leading to fluid leakage and reduced efficiency.
- Cylinder Damage: Caused by abrasive particles in the drilling fluid.
- Fatigue and Breakage: Particularly under high-pressure conditions.
