The piston assembly are forged by high quaility alloy constructional steel.
For Triplex&Duplex mud pumps piston cores are made of normalized carbon steel forgings.Clearances of piston core and liner bore are kept below 010”.Piston rubber cup is of fluid king design.It features a stronger lip as compared to the cantileverd sharp lip.It also can extend the life of pitons and liners.
In order to meet the demands of different petroleum drilling rechnology,we have studied and developed the new model piston assembly with good properties with high-temperature,high-pressure resistance,and high-antification.
