MKP’s Chrome Sleeve and Zirconia Ceramic Liners are designed to be interchangeable with OEM triplex pumps. All our liners are made with a high strength forged steel shell machined to fit triplex pumps and fitted with high pressure lip sleeve. The liner is precision machined to exact tolerances to keep the liner concentric. The sleeve is manufactured to the bore tolerances specified by API to provide longer life by reducing gaps between the liner bore and piston. After the shell and sleeve are assembled, the I.D. of the liner is honed to a perfect circle and polished to a mirror finish.
