3NB1300C mud pump Bi-metal liner

Bimetal liners are made of wear-resistant cast iron, and the surface hardness is HRC60-65. Therefore, liners feature wear resistance, corrosion resistance and high surface finish.

Liners are putted in from the cylinder cover bore in the front of the cylinder and fixed with liner cage, cylinder cover plug and cylinder cover when installing. 

Bimentle liners combine the strength of a forged steel outer shell with the abrasion and corrosion resistance of a high chromium iron inner sleeve.
