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