Audited Supplier API 7K Mud Pump Rubber Piston Drilling Mud Pump Parts Piston Assembly
Our 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 has higher temperature resistance, superior resistance to tear, abrasion and extrusion, and it increases run times even at pressures up to 7,500 psi. It delivers increased toughness, and is capable of operating in fluid temperatures up to 230°F (110°C) while maintaining high mechanical properties. It is interchangeable with all other API standard designed pistons. The piston offers superior performance at a moderate price, resulting in reduced cost per pumping hour.
The inner hole of the piston of the metric pump F500 is 25.4,F800-1300 is 42.1, the inner hole of the British piston is 38.1, F800-1300 is 41.3, and the material of the piston core is 42RrMo.
