Product Description
Specifications 1. Including piston hub, plate, snap ring and replacement rubber
2. Drawings provided to confirm
3. API-7K Certified
API Spec 7K oil drilling Mud Pump Piston Assembly 1.The function of the piston is working under high temperature, high pressure and bad lubricationconditions. 2.The pistons are fully interchangeable with other API standard designed pistons and deliver maximum performance in almost all drilling conditions. The hub is formed from high grade steel. The piston rubber is made from specially formulated compounds which are resistant to the effects of heat,oil and water. 3.The multi-ply fabric reinforced backings used in the production of the piston rubbers provide positive,wear resistant seals. High tensile strength, resistance to chemicals, hydrocarbic. Feature: 1. The piston assembly are forged by high quality alloy constructional steel. 2. The machinery performance of products is improved after heat treatment, phosphorization and zincification. 3. Model Number: 120mm, 130mm, 140mm, 150mm, 160mm.
