The outer hull, or body, of the liner is manufactured using high-strength forging. ROSENWELL uses forgings exclusively to ensure consistent quality. The sleeve is centrifugally cast in the ROSENWELL facilities by skilled engineers. It has the maximum amount of chrome for the base metal and ROSENWELL adds molybdenum to increase the hardness depth. The sleeve is then inserted into the hull at a tightness at exceeds its counterparts. The ROSENWELL liner is rated to match the pressure rating of the pump per liner size. ROSENWELL mud pump liners are unsurpassed in quality and reliability.

The outer sleeve is forged steel with quality carbon steel,the inner sleeve is casted with high carbon and high chromium use the technology of centrigual casting, after treatment ,the hardness of it can reach to a level of 59-67HRC.
