Slurry Pump

Central to slurry transport. Impellers, throatbushes and volutes face erosion, cavitation and corrosion. Select high-chromium iron or elastomers for the duty at each wear location.

Centrifugal slurry pumps transport solids-bearing fluids such as mineral slurry, ash slurry and mud. Wear is concentrated in the impeller, casing liners, side liners and throatbush. Select metal or elastomer materials for particle characteristics, solids concentration, temperature and corrosiveness.

Materials for similarly named parts may differ by OEM, machine model and operating conditions. Confirm the machine model, OEM drawing number and measured dimensions before ordering or manufacture.

Material Information

  • A05 is a Warman high-chromium white iron designation for applicable abrasive duties. Confirm the composition, heat treatment and hardness of replacement material against the part specification.
  • A49 is a Warman high-chromium white iron designation for more corrosive environments. Select for combined erosion and corrosion; it is not simply a more abrasion-resistant substitute for A05.
  • R26/R55 are original rubber material designations. Specify the exact grade, particle shape and size, temperature, speed and fluid compatibility when ordering.
  • R08 is an original natural rubber material designation. Verify chemical compatibility for the specific compound and operating conditions.
  • Ceramic coatings: a shaft sleeve surface treatment option for improved wear resistance.

Brand Applicability
