Product Overview
The mud pump cylinder liner is one of the core vulnerable parts of the drilling mud pump fluid cylinder system. It works in conjunction with the piston to form a high-pressure sealed cavity and operates under extremely high pressure and intense mud erosion. Our company offers a full range of products including bimetallic cylinder liners, ceramic cylinder liners, quenched/high-chromium cast iron cylinder liners, etc. We carefully select high-quality forged outer sleeves and wear-resistant inner linings, which feature extremely high compressive strength, wear resistance and corrosion resistance. They can significantly extend service life and reduce maintenance costs during shutdown.

Performance features and advantages |
Bimetallic cylinder liner
(Bimetallic Liner) |
Coat: 45# forged steel /40Cr
Inner lining: High-chromium cast iron (Cr>26%) |
Metric system: φ100 to φ220mm
Imperial system: 3.5" to 7" |
≤ 34.5 MPa (5000 PSI) |
High wear resistance, with a hardness of HRC 60-67 |
The mainstream standard configuration in the industry, with high tensile strength of the outer jacket and extremely high hardness of the inner lining, offers excellent cost performance and a service life of over 800 hours. |
Zirconia ceramic cylinder liner
(Zirconia Ceramic Liner) |
Coat: 45# forged steel
Inner lining: Zirconia (ZrO2) ceramic |
Metric system: φ100 to φ200mm
Imperial system: 3.5" to 7" |
≤ 52.0 MPa (7500 PSI) |
Ultra-high wear resistance and super corrosion resistance |
The wear resistance is 5 to 10 times that of bimetallic cylinder liners, with an extremely low coefficient of friction, which can significantly extend the service life of the piston and has a low overall usage cost. |
Alumina ceramic cylinder liner
(Alumina Ceramic Liner) |
Coat: 45# forged steel
Inner lining: alumina (Al2O3) ceramic |
Metric system: φ100 to φ200mm
Imperial system: 3.5" to 7" |
≤ 34.5 MPa (5000 PSI) |
High wear resistance and excellent corrosion resistance |
It has strong corrosion resistance and is suitable for harsh mud conditions such as strong acids and strong alkalis. Its cost performance is superior to that of zirconia ceramic cylinder liners. |
High-chromium/high-frequency quenched cylinder liner
(High Chrome / Hardened Liner) |
45# Forged steel/High-quality alloy steel
(Overall carburizing/quenching |
Metric system: φ100 to φ220mm
Imperial system: 3.5" to 7" |
≤ 25.0 MPa (3600 PSI) |
Medium to high wear resistance, hardness HRC 58-62 |
It is suitable for shallow Wells, ordinary onshore drilling and medium and low pressure working conditions, with low procurement cost and economic practicality. |

Ordering Instructions
When placing an order, please specify the model of the mud pump (such as F-1600) and the required inner diameter of the cylinder liner (such as 170mm or 6-3/4").
2. Please describe the working conditions (such as the type of slurry, corrosiveness and high-pressure requirements) so that we can recommend the most suitable material (bimetallic or ceramic) for you.
