Mud Pump Liner and Piston

LINERS FOR TRIPLEX AND DUPLEX MUD PUMP

Zirconia ceramic liner, high chrome liner, hardened steel liner, chrome-plated liner are with the best performance and durability for tough and challenging terrain and conditions. 

With advanced technology, metallurgical control and rigid inspection, all type of liners are available in all series of size with unparallel cost performance ratio.


Zirconia Ceramic Liners

Zirconia ceramic liners are for most severe drilling application and offshore drilling condition.

Features

Higher hardness with wear resistance

Stronger erosion resistance

High pressure resistance

Lower friction with elastic and metal pump piston.

     

High chrome liner

Constructed to a computer designed shrink fit of a high chrome or bimetal sleeve into a forged steel hull, the liners offer extreme abrasion resistance, hardness and corrosion resistance.

Features

Inner sleeves are 26-28% chrome steel heat treated to 60 to 65 Rockwell C hardness

Liner bore tolerances, tighter than API specification.

Extreme long service life;

Digitally controlled CNC machining.


Chrome plated liner

Chrome plated liners matches performance and durability in tough and challenging working conditions.

Features

Premium forged alloy steel

Chrome plated by 0.010-0.015 depth.

58 to 62 Rockwell C hardness.

Digitally controlled CNC machining.

Long lasting service life.


PISTONS FOR TRIPLEX AND DUPLEX MUD PUMP

ETANG supplies full line of API taper pistons for both triplex and duplex mud pump. With versatile options of replaceable rubber, urethane or bonded urethane piston. Feedback record shows our customers are satisfied to our quality pistons.


BONDED URETHANE PISTONS

With most harsh drilling conditions and new synthetic mud introducing more corrosive chemicals, we discarded the design forced by rubber’s limitation and take full advantage of urethane’s strengths to realize a revolutionary design.

Feature

Designed with harder denser polyurethane construction.

High pressure mud pump service

Maximum operating temperature up to 180 ℉

Extended service life.


REPLACEBLE URETHANE PISTON 

Designed for high temperature drilling mud, these pistons are made of replaceable urethane mounted on solid hub with a plate and snap ring.

Features

Rated for all drilling operations.

Maximum operation temperature is 230℉
