Pumps & Valves

Pump & Valve CastingsSince 1984, Steloy Castings has specialised in the supply of as-cast and machined components for pumps and valve castings manufactured in stainless steels, nickel-based corrosion resistant alloys, carbon steels and low alloy steels for applications where severe corrosion, high pressure and high or cryogenic temperatures are prevalent.

 

Typical applications for pump and valve castings include:

  • Petrochemicals (exploration and refining)
  • Mining
  • Food & Beverage
  • Desalination, Fertiliser and Chemical Plants
  • Power Generation/Nuclear Power

Castings are produced at the three Steloy plants, all of which have access to centralised solidification analyses and modelling (MAGMASOFT) and CNC patternmaking capabilities. All components are produced in accordance with the relevant ASTM, DIN EN and SEW specifications and conform to applicable NACE specifications.
