Mud Pump Liner Types:

There are four main mud pump lines, like high frequency quenching liners, chromium-plated liners, ceramic liners, and bi-metal liners.

High Frequency Quenching Liners

The high frequency quenching liner is suitable to use in the condition of mild corrosive mud.

The liners are hardened and heat treated under strict quality control, the hardness can reach to a level of 60HRC.

The inner sleeve is highly polished, abrasion& corrosion resistance, thus have a long service life.

Chromium-plated Liners

The chorme-plated liner is made from premium forged steel with the bore plated by chrome. The hardness is 58-62HRC.

Ceramic Liners   

The ceramic liner is composed of two layers and fixed tightly. The outer sleeve is forged steel with abrasion resistance, the inner sleeve is ceramic.

The ceramic liner seems expensive but actually cut the cost of running mud pumps. Our ceramic liners are proved has a service life of 4000 hours.

Bi-metal Liners

The bi-metal liner is composed of two layers and fixed tightly. The outer sleeve is forged steel with abrasion resistance, it adapts the technology of centrifugal forging; the inner sleeve is high chromium iron with wear& corrosion resistance, after heat treatment, the hardness of it can reach to a lever of 62 RC.

The bi-metal liners produced by us strictly control the tolerance, assure the easy installation, inner sleeve is highly polished with abrasion& corrosive resistance, can used in various bad working environment with longer service life.
