Product details
The mud pump piston assembly is one of the main parts of the hydraulic end system of the mud pump, and it is also one of the vulnerable parts in the drilling work. The discharge pressure of the mud pump is generated by the reciprocating linear movement of the piston assembly in the piston. The piston assembly is composed of piston core, rubber, circlip, pressure plate, etc. The material of the piston core is 42CrMo, and the material of the piston rubber is nitrile rubber or polyurethane rubber.
Nitrile rubber is suitable for ordinary drilling working environment with working pressure below 20Mpa, and the working temperature is not higher than 120℃. Excellent wear resistance, chemical resistance, long service life in ordinary drilling working environment.
Polyurethane rubber has excellent oil resistance and wear resistance. The working temperature is not higher than 120℃, which is suitable for oil-based mud with working pressure below 35Mpa and working environment with high sand content.
