5 x 4in, Centrifugal Fire Pump (SFP-400-54 EM-2G)

The centrifugal fire pump model SFP-400-54 EM-2G is an end suction pump designed for high efficiency and reliability in fire protection systems. It operates at a frequency of 50/60 Hz and features a top centerline discharge, which ensures optimal flow characteristics. The pump is built with a foot-supported casing and a back pullout design for easy maintenance. It has a self-venting design to prevent air entrapment and an efficiently designed impeller for enhanced performance. The frame-mounted design with a small footprint makes it suitable for retrofit applications. The dynamically balanced impeller ensures smooth operation, and the pump’s heavy-duty construction with thick walls guarantees durability. Each unit undergoes 100% hydrostatic and performance testing to ensure quality. The casing can be made of cast iron or ductile iron, while the impeller is available in bronze or duplex upon request. The shaft options include alloy steel, stainless steel, or duplex. This pump offers capacities ranging from 50 to 1000 GPM and pressures from 65 to 234 PSI, with a maximum working pressure between 180 and 315 PSI. It operates at speeds of 2900, 3000, 3500, and 3600 RPM. The model is UL listed and has a rated capacity of 400 GPM, with a flange size of 5 x 4 inches, a rated net pressure range of 137 to 215 PSI, and a maximum working pressure of 315 PSI.
