Sandpiper S15 pumps are available in three metal fabrications, aluminum, cast iron and stainless steel, with different materials to meet handling needs. Pumps with Urethane have good resistance to abrasives but low resistance to oils and solvents. Maximum operating temperature for Urethane is 150º F / 66º C. Performance ratings are based on an elastomer fitted pump and water at ambient conditions.
Pumps using Conductive Acetal are impact resistant with good abrasion resistance. This material also has good chemical resistance except for strong acids or oxidizers. Maximum operating temperature for Conductive Acetal is 190º F / 88º C. Other choices in materials include Virgin PTFE, Santoprene, Hytrel, Polypropylene, FKM (Fluorocarbon), Neoprene, PVDF, Nylon and UHMW PE.
All Sandpiper pumps are manufactured under ISO 14001 Environmental Management and ISO 9001 Quality certifications. An optional 8-foot ground strap should be used for ATEX compliance. Modification kits may be required depending on material chosen. A 5-year limited warranty is provided for the Sandpiper S15 metal pump.
