mud pump piston

1.Piston Assy

a.Application
Piston assembly is used as a type of mud pump fluid end accessories in the oil drilling industry.

b.Materials
The main body of the piston assembly is made of forged steel 45# or 40Cr, and the piston cup and rubber are of high polymer materials.

c.Advantages
In order to accommodate every drilling need in various oil fields, we at Rundong have developed superior piston assembly for customers. Our piston assembly offers the advantages of reliable performance, strong wear and hydrolysis resistance under high temperature and high pressure.

3.Mud pump piston assy (piston assy)

These pistons are made with tough and durable NBR for all pressures, and are ideally suited for either oil-base or water-base mud.

A special processing of the fabric provides an unusually waterproof bond of fabric to piston which assures longer life. These high tensile strength pistons will be rated for all drilling operations.

As one of piston part , Piston hub is forged by high quality alloy constructional steel, such as ASTM 1045.

1. The machinery performance is improved after heat-treatment , phosphorization and zincification.
2. A long working life of 200--500 hrs
3. piston cup material: PU / NBR
4. API 4# , 5#, 6#, 7#

4.Four series piston assy

The piston assembly was made of forging steel 45# or 55 Mn,and piston rubber was made of import high molecular materials by Dezhou Rundong Petroleum Machinery Co.,Ltd.

In order to meet the demands of different petroleum drilling technology, Dezhou Rundong Petroleum Machinery Co.,Ltd.has studied and developed the new model piston assembly with good properties of high-temperature,high-pressure resistance,high anti-friction.
