HIGH CHROME SLEEVE LINER

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

Kunhec mud pump liners are the best, “Bar None.”
