Liner

High Chromium Sleeve Liners
China star High Chrome Sleeve Liners combine the strength of a forged steel outer hull with the abrasion and corrosion resistance of a high chromium iron inner sleeve. The sleeve is centrifugally cast in our own facilities and is honed to a mirror-like finish. Our High Chrome Sleeve Liners have minimum uniform bore hardness of 62 RC. They feature “HP” design to prevent inner sleeve slippage. Star High Chrome Sleeve liners are tougher and last longer than our competitors.

.                                                                           Single Shell Liners
Single shell Liners are made of outer hull with inner surface treatment instead of sleeve. After the inner bore is nitro carbonized, it is quenched through medium and high frequency to make the surface hardness reach 60RC. Chromium can be further plated to make surface hardness exceeds 62RC. Then the inner surface is honed to a mirror-like finish. Star Chromium Plated Liners have high hardness, high corrosion resistance, free deformation and best surface finish.

Zirconia Ceramic Liners
China star Zirconia Ceramic Liners feature a forged steel outer hull and a Zirconia inner sleeve. They come in a variety of sizes and fit in all major brand mud pumps. They offer lifetime cost savings, significantly longer service, better performance and safer operation. The special hardness and exceptional wear resistance of Zirconia also translates into longer service from the urethane and rubber pistons.
