The chrome-plated liners have hardening characteristics of 58 to 62 Rockwell C hardness.
KH-chrome mud pump liners are made with a high chrome iron sleeve in a forged steel hull.The bore hardness is 60 to 67 Rockwell C scales while the hull has high tensile strength of more than 90000psi.Combining the characteristics of chrome with state of the art manufacturing,the liners can withstand mud pressure of up to 7000psi.The life of our KH-chrome liners is proved to generally reach a level of more than 800 hours,which has earned us reputation from worldwide customer
