Product Description

Unbt Series Mud Pump Liner Cylinder Liner

premium liners combine the strength of a forged steel outer shell with the abrasion and corrosion reisistance of a high chromium iron inner sleeve. The liners feature a centrifugally cast high chrome iron sleeve which is machined and heat treated to a minmum uniform bore hardness of HRC62.
The inner surface of the liners with a mirror-like smooth finish and the inner holes' dimension tolerance is strictly controlled to ensure a long using life of more than 800 hours.

Bimetal Liners
The b-metal liner is composed of two layers and fixed tightly. The outer sleeve is forged steel with abrasion resistance, it adapts the technology of centrigugal 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 bimetal 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. 
Liner Outer Sleeve: 45#forged steel, tensile strength is σb>610MPa, yield strength is σs>450MPa, ,elongation hardness is §>17%,hardness is HRC180-200
Liner Inner Sleeve: high chromium cast iron (centrifugal forged). Annealing hardness is HRC≤40. Quenching hardness is HRC59-67
Chemical Composition:C 2.8%-3.1%  Cr 26%-28%  Si 0.6%-0.9%  Mn 0.5%-1% Mo 0.5%-0.8% S , P <0.05%;
