Rubber Piston, Dual-Hardness Overall Vulcanized Piston for Oilfield Mud Pump Parts

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.   Our mud pump pistons are strictly manufactured according to API Standard, which with a high performance in various well drilling environment. The hub is forged from high quality steel, and the piston rubber is made from specially formulated compounds which are of heat, oil and water resistance. It is interchangeable with all other API standard designed pistons. And the valve rubber is easy to install.   TypeHub MaterialCup MaterialHub surface treatmentSizeBonded pistons, Replaceable pistonsForged by 45# steel , 40Cr with hardening and tempering Urethane NBR rubberPhosphating & by Oxidizing3-8''     DescriptionTemperature RangePump PressureAbrasionDrilling FluidNBR-40~100 °C5000PSI(35Mpa)Not BadWater base-40~210 °Fpolyurethane-40~85 °C5000PSI(35Mpa)ExcellentWater base & Oil base-40~185 °FHNBR-50~150 °C7500PSI(52Mpa)GoodWater base & Oil base-58~300 °F FAQ                                         How to order?Please send us your inquiry with detail item description or with Model number.If there is no packing demand we take it as our regular exported standard packing.We will offer you an order form for filling.
