Performance Improvement Program for Pumps

In an effort to improve pump performance and extend service life on old and new pumps, Belzona has developed the pump performance improvement program.

  • Performance gains range from 7% on new pumps to 40% on those in service
  • Reductions in operating costs can be realized immediately
  • Pumps protected with Belzona systems are certain to last longer
  • Belzona systems resist the damaging effects of erosion/corrosion, abrasion, and chemical attack that destroy cast iron, steel, bronze, and other materials of construction
  • Worn pump components can be easily rebuilt and/or coated at much lower cost when compared to direct part replacement
  • Ability for refurbishment of scrap components with minimal downtime

Split Casing Pump

  • Rebuild and coat erosion/corrosion damage to maintain or increase original efficiency of the pump by providing a tough erosion/corrosion and chemical resistant surface
  • Repair holed or cracked casings by stopping leaks, restoring structural integrity, and protecting against future erosion damage
  • Reconstruct worn cutwater profiles to provide outstanding resistance to future erosion/corrosion, without inducing bi-metallic corrosion
  • Repair impeller wear ring clearances by acting as an electrical insulator for the components, eliminating bi-metallic corrosion
  • Repair impeller vane erosion by accurately restoring lost profiles and providing greater erosion/corrosion resistance than the original material
 

End Suction Pump

  • Repair erosion/corrosion damage to maintain or increase original efficiency of the pump by providing a tough erosion/corrosion and chemical resistant surface
  • Repair and protect impellers to resist cavitation and prevent recurrence of the problem
  • Rebuild damaged end covers by reconstructing the profiles, precisely restoring the critical clearances
  • Rebuild, re-profile and protect eroded flow straighteners which will result in a surface more resistant to erosion/corrosion than the parent metal
 

Diffuser Pump

  • Restore bearing and packing seats which will be highly erosion and corrosion resistant, and completely insulated from bi-metallic corrosion
  • Rebuild water lubricated bearings to exhibit outstanding abrasion resistance
  • Repair and restore vane profiles to offer greater resistance to impingement and entrainment damage
  • Repair and protect impellers to resist cavitation and prevent recurrence of the problem
 

Liquid Ring Vacuum Pump

  • Rebuild and restore vacuum pump rotors to provide erosion/corrosion and chemical resistance to protect the rotor and prevent recurrence of the problem
  • Rebuild cone clearances resulting in a surface that is highly resistant to corrosion, chemical attack, and abrasion by solids entrainment in the water ring seal and can often outlast original cones
  • Restore casings and prevent future damage by applying abrasion or chemical resistant coating
  • Rebuild valve plates to restore the required profiles with minimal machining
  • Restore end covers resulting in surfaces that have excellent resistance to chemicals and abrasion, thus extending the life of the end covers and eliminating the need for expensive replacement
