Bimetal Liner Inner sleeve: high chromium alloy steel Outer sleeve: forged alloy steel Hardness: greater than 60HRC

Bimetal liner

Material: The material of cylinder liner is ZG45 steel, lined with high chromium cast iron. The HRC of cylinder inside liner is 60-65.

Production Process: The bi-metal cylinder Liner of our company combined with the advantages of abrasion hot-forging out liner and anticorrosion high chrome inner liner. The out liner is made of high quality carbon steel by hot pressing forming. Its tensile strength is over 900000psi. The inner liner is made of high-chromium alloy by centrifugal casting.

Application: Bi-metal cylinder liner is one of the most widely and largest used mud pump fluid end fittings.

High Quality Mud Pump Parts, Different Size Liner, Ceramic Liner
Mud Pump Liners

Mud pump liners are including Bi-metal Liners and Ceramic Liners. Sizes of 6 1/2”, 7”, 140mm, 150mm,160mm, 170mm, 200mm, 230mm liners.

Description:
Bi-metal Liners combine the strength of a forged steel outer shell with the abrasion and corrosion resistance of a high chrome inner sleeve. These liners feature a centrifugally cast high chrome iron sleeve which is machined and heat treated to a minimum uniform bore hardness of 59-65HRC.
