Piston rubber -mud pump parts

Piston rubber characterics

Normal Standard

All pistons are produced by imported acrylonitrile butadiene rubber which suit for ordinary drilling environment . The working temperature of our piston is up to 120 and it is with excellent wear resistance and good chemical corrosion resistant .The service life of the piston can reach 280 hours in ordinary drilling working environment.

Strength Enhanced

The material of this kind of pistons is high-intensity acrylonitrile butadiene rubber which supplyed by 

American Dupont company and Japanese Zeon company. This kind of pistions is with good oil and 

wear resistance as well as super comprehensive strength, which applied to oil-based mud and higher silt content working environment.

High-temperature and High-hydrogen sulfide

The material of this kind of pistons is HNBR supplyed by American DuPont company and Japanese Zeon company which applied to high-temperature, high pressure, high-corrosion working environment. The working temperature is up to 150. Generally, HNBR is usually used for aviation industry and it was also used for the oil industry in recent years, HNBR has excellent wear resistance, chemical resistance and oil resistance of performance. Its amine resistance properties and steam resistance performance are very good. Especially in high-temperature, high-pressure working environment. The ordinary rubber is easy damaged for the role of hydrogen sulfide, carbon dioxide, methane, steam and acid environment, but HNBR has shown a good comprehensive performance.
