The SFP 750-SN 3 1SH is a robust split-case centrifugal fire pump designed for high-efficiency fire protection applications. This pump operates at 50/60 Hz and features a volute type thru-bore casing, optimizing fluid dynamics for enhanced performance. It is frame-mounted for stability and ease of installation, with a small footprint making it ideal for retrofit projects. Constructed with heavy-duty thick walls, the pump is built to endure tough conditions and provide long-term service. Each unit is 100% hydrostatic and performance tested to ensure reliability and adherence to stringent standards. The dynamically balanced double suction impeller enhances operational efficiency and stability. The casing can be made from cast iron or ductile iron, and the impeller is available in bronze or duplex upon request. Shaft material options include alloy steel, stainless steel, and duplex. The pump offers a capacity range from 150 GPM to 3500 GPM, with 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 versatile for various fire protection needs.
