6 x 4 Inches,Split Case Centrifugal Fire Pump (SFP 250-SN 3 1SH)

The SFP 250-SN 3 1SH centrifugal fire pump is a robust split case pump suitable for both 50 Hz and 60 Hz frequencies. It features a volute type thru-bore casing made from cast iron or ductile iron, providing exceptional durability and performance under demanding conditions. The pump’s frame-mounted design, along with its compact footprint, makes it ideal for retrofit applications where space is at a premium. Constructed with heavy-duty, thick-walled materials, this pump is engineered to handle high pressures and rigorous operational demands. Each pump undergoes comprehensive hydrostatic and performance testing to ensure reliability and efficiency. The dynamically balanced double suction impeller, available in bronze or duplex upon request, ensures smooth and efficient fluid flow. The shaft can be made from alloy steel, stainless steel, or duplex, based on specific requirements. This model supports a capacity range of 150 to 3500 GPM, pressure range of 88 to 335 PSI, and a maximum working pressure between 220 to 410 PSI. It operates at speeds of 2900, 3000, 3500, and 3600 RPM. Specifically, the SFP 250-SN 3 1SH model delivers a rated capacity of 250 GPM with a flange size of 6 x 4 inches. At 3500 RPM, it operates within a net pressure range of 226 to 317 PSI, and at 3600 RPM, the pressure range is 239 to 335 PSI, with a maximum working pressure of 405 PSI.
