MUD PUMP PARTS

Mud pumps are critical equipment in oil drilling operations, primarily used to pump drilling fluid (mud) from the surface to the bottom of the well, performing important functions such as cooling the drill bit, carrying cuttings, and stabilizing the wellbore. To ensure long-term stable operation in high-pressure, high-wear environments, mud pumps are composed of multiple precision components, typically divided into two major components: the fluid end and the power end.

BI-METAL
LINERS

High-strength liners built for heavy-duty drilling—wear-resistant, API 7K compliant, and long-lasting.
