Cylinder Liner for A-1100-PT Mud Pump

Category: Tags: , , , ,


The outer section or shell is manufactured from high strength carbon steel and heat-treated to provide optimum mechanical properties. The inner section or sleeve, is manufactured from a proprietary high chrome content iron alloy that offers excellent resistance to wear. The high percentage and thorough distribution of chrome carbides in conjunction with controlled heat treatment for maximum metallurgical properties, prior to assembly in the shell, gives a very high degree of uniformity in microstructure and wall section hardness. This results in a sleeve that has excellent abrasion, erosion and corrosion resistance. The sleeve is manufactured to the bore tolerances specified by API or better to provide longer life by reducing gaps between the liner bore and piston.

Service Life: more than 800 hours


Rated for all drilling operations.
Bore hardness is 62-69 Rockwell.
HP lip design to prevent inner sleeve slippage.
Excellent resistance to abrasion, erosion and corrosion.
Extremely long service life.


Our Ceramic Liners offer longer run times, lower operating costs and reduced risk exposure when compared to operating with chrome iron liners.

The ceramic sleeve material is manufactured from alumina oxide, known for its wear resistance, and has proven run times in all types of operating conditions. The outer hull material for large bore liners is manufactured from alloy steel to increase yield strength and aid in fatigue resistance. Our ceramic liners are corrosion resistant and have a smoother surface finish for reduced friction and heat.

Service Life: more than 800 hours

“HP” Design with shoulder on hull to prevent sleeve slippage.
ID tolerances is +.010″/-.000″
Surface ¬finish 4-8 RMS
Expected run life exceeding 10,000 hours
Hardness: HV 0.3 kg/mm – 1100/1200 (92-94 Rc)
– (Chrome sleeved liners are 60-64 Rc)
Ceramic liners do not create ID ridges which are common in high chrome liners.
-ID ridges are a cause of piston failures.
-Ceramic liners improve piston run life.
Ceramic liners are pressure rated to pump performance by piston size.
Liners are available in sizes 4-1/2″ to 8″.
Liners are available for popular pumps.
