Mud pump Bonded Urethane Piston - piston rubber directly vulcanized on the steel core, without pressure plate and spring, widely applicable to what kind of mud pump conditions, especially for high-pressure jet drilling and ceramic liner.

the assembled piston-piston core is forged by 40Cr and heat-treated. the rubber is made of polyurethane, butadiene cyanide rubber or hydrogenated butadiene cyanide rubber.

in addition, we can also produce double cylinder pump piston.

Nitrile rubber

Suitable for ordinary drilling pressure below 20 mpa working environment, working temperature is not higher than 120.Excellent wear resistance, chemical corrosion resistance, long service life in common drilling environment.

Polyurethane rubber

Excellent oil resistance and wear resistance.Working temperature is not higher than 120, be applicable to the working pressure of oil-base mud under 35 mpa and sediment concentration higher working environment.

Hydrogenated nitrile rubber

Suitable for high temperature and high pressure, high corrosion environment, working pressure of 75 mpa, the working temperature is 150.Hydrogenated nitrile rubber is a kind of rubber used in aviation.Used in petroleum industry, hydrogenated nitrile butadiene rubber has good wear resistance, oil resistance, chemical resistance, amine resistance and steam resistance.Especially in the working environment of high temperature and high pressure, other rubber will be destroyed quickly under the action of hydrogen sulfide, carbon dioxide, methane, steam and acid, but hydrogenated nitrile rubber shows good comprehensive performance.
