6 x 4 inches, Split Case Centrifugal Fire Pump (SFP 250-25SH)

The SFP 250-25SH centrifugal fire pump is a highly efficient split case pump designed for fire protection applications, operating on both 50 Hz and 60 Hz frequencies. It features a volute type thru-bore casing, available in cast iron or ductile iron, ensuring robust durability. The pump’s frame-mounted design and compact footprint make it ideal for retrofit projects where space is a constraint. Constructed with heavy-duty, thick-walled materials, the pump is built to withstand high pressures and rigorous conditions. Each unit undergoes 100% hydrostatic and performance testing to ensure reliability and efficiency. The dynamically balanced double suction impeller, available in bronze or duplex material upon request, ensures smooth and efficient operation. The shaft is available in alloy steel, stainless steel, or duplex, depending on customer requirements. The pump has a capacity range of 150 to 3500 GPM, pressure handling from 88 to 335 PSI, and can withstand maximum working pressures from 220 to 410 PSI. Operating speeds are available at 2900, 3000, 3500, and 3600 RPM. The SFP 250-25SH model specifically delivers a rated capacity of 250 GPM with a flange size of 6 x 4 inches. It operates at speeds of 3500 RPM with a net pressure range of 114 to 207 PSI and at 3600 RPM with a net pressure range of 121 to 219 PSI, with a maximum working pressure of 300 PSI.
