A mud pump liner is a component of a mud pump that is responsible for sealing the drilling fluid in the mud pump mudule. It is one of the most critical parts of the mud pump parts, and its failure can lead to significant downtime and costly repairs. Mud pump liners are available in various materials, including ceramic, chrome iron, and hardened steel.

Types of mud pump liner
The types of the mud pump liner were Bimetal liner and Ceramic liner.
Bimetal liners are the most common type of cylinder liner, while ceramic liners have a longer service life but are expensive.
Types of mud pump Bimetal liner
There are two kinds of LONGWELL’s Bimetal liners: high chrome liner and High-frequency quenching liner.
The former is made of carbon steel. The inside of it is plated with high-chrome alloy-steel to have good wear ability.
LONGWELL Mud Pump metallic liner sleeves are structured with maximum amount of chrome for the base metal, inserted into the forged steel hull at full tension.

And the latter is made by High-frequency quenching. The inside of the mud pump liner is cemented and hardened to enhance the surface hardness, High-frequency process has a higher cost-effectiveness.
The outer rust prevention uses high-temperature phosphating process, without painting, which has better corrosion resistance and is more environmentally friendly.

High-frequency quenching mud pump liner
Feature of LONGWELL’s Bimetal mud pump liner
The bore hardness is 60 to 67 Rockwell C scales, while the hull has a higher tensile strength of more than 90,000 psi.
liners with these high-quality characteristics can withstand mud pressure up to 7,000 psi and rated to match the pressure rating of the pump per liner size with more than 800 hours of working life under normal environment.
Feature of LONGWELL’s mud pump ceramic liner
LONGWELL Mud Pump ceramic liners are designed to use in harsh environments.
The Liner sleeve is made from ceramic/zirconia material that extends the service life compared to regular steel liners.
With this unique material, service life can reach more than 4000 hours.
This results in less oil rig downtime and offers more efficient budget cost per operating hour, which also reduces piston wear and water consumption for lubrication.
Size of mud pump liner
There are six sizes of liners with an increment of 10mm or 0.5 inch in I. D. All these liners are the same in O.D.
