The outer hull, or body, of the liner is a high strength forging. We uses forgings exclusively to ensure the consistent quality. The sleeve is centrifugally casted in the our facilities by skilled craftsmen. It has the maximum amount of chrome for the base metal and we adds molybdenum to increase the hardness depth. The sleeve is then inserted into the hull at a tightness that exceeds its counterparts. The liner is rated to match the pressure rating of the pump per liner size. Our mud pump liners are designed and manufactured to meet or exceed the original equipment specifications and API standards for almost all types of mud pumps in the world. With advanced technology, metallurgical control and rigid inspection, both triplex and duplex liners are available in a wide range of sizes with unmatched performance and durability in the most severe drilling conditions.
