Bi-Metal Mud Pump Liner (6-inch)

The Bi-Metal mud pump liner is a critical wear part in drilling mud circulation systems. The outer shell is forged from high-quality carbon steel, while the inner sleeve is a high-chrome iron alloy with hardness reaching 60+ HRC. The inner bore is produced via centrifugal casting and precision honing, providing a high-gloss finish that reduces friction with the piston. Rated for 7,500 psi, it resists abrasion from high-pressure, corrosive mud and solid particles, offering an exceptionally long service life for global drilling pump brands.
