Core Products

Our factory is certified with the ISO 9001 Quality Management System

Mud Pump Crosshead

Mud Pump Crosshead (for F-500/800/1000/1300/1600 and other models)

The crosshead is a vital component of the mud pump power end. It converts the rotary motion of the crankshaft (via the connecting rod) into linear reciprocating motion, then transmits power to the piston through the extension rod to drive the fluid end.

Upper Guide Board

Upper Guide Board (for 3NB-350/500/800/1000/1300/1600 Mud Pump)

The upper guide board (also called upper guide plate) is a critical wear component in the power end of the 3NB series triplex mud pump. Its primary function is to guide and constrain the crosshead assembly, ensuring perfectly straight linear motion along the pump’s centerline.

Extension Rod

Extension Rod

The Extension Rod is a key connecting component of the fluid end of the mud pump. It is mainly used to connect the piston rod and the crosshead, transmit power, compensate for installation gaps, and ensure the smoothness and continuity of the reciprocating movement of the mud pump.
