The SFP 750-31SM is a high-performance split-case centrifugal fire pump designed for effective fire protection. Operating at a frequency of 50/60 Hz, it features a volute type thru-bore casing, which ensures efficient fluid dynamics. The pump is frame-mounted, providing a stable and robust design, and has a small footprint that is ideal for retrofit applications. Constructed with heavy-duty materials and a thick wall casing, this pump is built to withstand demanding conditions. Each unit undergoes 100% hydrostatic and performance testing to guarantee reliability and safety. The dynamically balanced double suction impeller ensures smooth and efficient operation. The casing is available in cast iron or ductile iron, while the impeller can be made of bronze or duplex upon request. The shaft is available in alloy steel, stainless steel, or duplex, providing flexibility for various requirements. The pump has a capacity range from 150 GPM to 3500 GPM, a pressure range of 88 to 335 PSI, and a maximum working pressure of 220 to 410 PSI. It operates at speeds of 2900, 3000, 3500, and 3600 RPM, making it suitable for diverse operational needs.
