The SFP 500-SN 3 1SH is a high-performance split-case centrifugal fire pump, meticulously crafted to meet the stringent requirements of fire protection systems. Designed to operate at both 50 and 60 Hz, it features a volute type thru-bore casing that enhances its operational efficiency. The pump is frame-mounted, making it a robust and durable option with a small footprint that is ideal for retrofit applications. Constructed with heavy-duty materials and a thick wall casing, it ensures long-lasting performance. Each unit undergoes 100% hydrostatic and performance testing to ensure reliability under critical conditions. The pump is equipped with a dynamically balanced double suction impeller, available in bronze or duplex upon request. The casing is made of cast iron or ductile iron, and the shaft material can be customized to alloy steel, stainless steel, or duplex based on specific needs. The pump offers a capacity range of 150 to 3500 GPM and a pressure range of 88 to 335 PSI, with a maximum working pressure of 220 to 410 PSI. It operates at speeds of 2900, 3000, 3500, and 3600 RPM.
