Pumps & Valves

Pumps Castings & Valve ComponentsSteloy Castings has been the preferred supplier of as-cast and machined pump castings and valve components since 1984. We manufacture cast pumps and valves in several grades of stainless steels to cater for the demands of an array of industries, including oil and gas, desalination, chemical, nuclear and waste.

Our commitment to quality sees all products being manufactured in accordance with the highest international standards and conforming to NACE specifications. This allows us to ensure maximum integrity and performance for applications where severe corrosion, high pressures and high or cryogenic temperatures are prevalent. In addition, our castings carry European Pressure Equipment Directive (PED) accreditation, ratified by TÜV Rheinland, to assist OEMs in producing pressurised systems to CE requirements.

Steloy’s pump and valve casting expertise for the local market ensures the production of components that add value to the final product, offering a longer lifespan and durability for pumps and valves that offer high levels of stress, corrosion, abrasion and wear resistance.

Over the years, we have supported the operations of numerous pump and valve manufacturing companies, including Sulzer Pumps, KSB, Weir, Spirax, Sarco, AZ Armaturen, Flowserve, Allis Chalmers (Goulds), Tomoe, Samco and Gunric.
