The mud pump piston assembly is one of the main parts of the hydraulic end system of the mud pump. The discharge pressure of the mud pump is generated by reciprocating linear motion of the piston assembly in the piston. Piston assembly by the piston core, rubber, spring, pressure plate, etc.

Main Features
1. Corrosion-resistant, capable of operate with the oil and water base drilling mud or other corrosive liquid etc.
2. Wear resistance, capable of working with high pressure mud with solid particles ,such as rock cuttings , quartz sands.
3. long operation time due to the robust material and treatment of rubber.
