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.

LONGWELL is a company that provides high-quality mud pump parts, including mud pump liners. Their mud pump liners are 100% interchangeable with the most common brands of mud pumps and have a long-lasting service life of up to 4000 hours. They can be used around 7500 psi of working pressure and also provide reliable liner packing seal rings and mud pump piston. Customized liners according to drawings can be produced as well.

Mud pump liners are replaceable components within a mud pump that directly interact with the drilling fluid or “mud.” These liners fit inside the cylinder of the mud pump and serve several important functions:
Sealing: Mud pump liners ensure a tight seal between the piston and the cylinder wall, which is critical for maintaining the necessary pressure to push the mud effectively through the drilling system.
Withstanding Abrasion: Drilling mud can be highly abrasive due to the suspended solids and cuttings it carries from the borehole. Liners are designed to withstand this abrasion and protect the cylinder walls from excessive wear.

Heat Dissipation: The process of pumping high volumes of mud at high pressures generates heat. Liners often have cooling features or are made of materials that can handle and dissipate heat effectively.
Replaceability: Since they bear the brunt of the mechanical stress and wear during operation, mud pump liners are designed to be replaceable. This allows for maintenance and repair without having to replace the entire cylinder, which can be more costly and time-consuming.

Mud pump liners are typically made from durable materials like hardened steel or, in some cases, specialized wear-resistant alloys or even ceramic coatings to enhance their lifespan under harsh drilling conditions. Regular inspection and timely replacement of worn liners are essential to maintain the efficiency and safety of the mud pump operation.

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.

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.
