Coatings for Pumps



Hardide coatings offer pump manufacturers extended component life and enhanced performance in applications where the handling of chemically aggressive or abrasive fluid causes costly loss of production and downtime.

In one application, the coating has delivered a four-fold increase in life in positive displacement pumps handling viscous fluids containing abrasive pigments and fillers. It coats internal surfaces and complex shapes, offers facilitated finishing and reduces wear on packing seals.

Operational efficiency is improved on positive displacement pumps, drilling mud pumps, reciprocating pumps, progressive cavity pumps, multi-stage centrifugal pumps, lobe pumps and vane pumps.

Typical applications include:

  • Impellers
  • Housing
  • Vanes
  • Shafts
  • Cylinders
  • Plungers
  • Rotors
  • Sleeve bearings
