2 ½ x 1 ½ in Centrifugal Fire Pump (SFP 50-42 EH)

The centrifugal fire pump is designed for high efficiency and reliability in fire protection systems. Featuring an end suction configuration and top centerline discharge, it ensures stable and optimal performance with its foot-supported casing. The back pullout design facilitates easy maintenance without disrupting the piping system. This pump’s self-venting design, dynamically balanced impeller, and heavy-duty construction make it suitable for rigorous applications. The frame-mounted design and small footprint make it ideal for retrofit installations. Constructed with a cast iron or ductile iron casing and a bronze or duplex impeller, the pump also offers options for alloy steel, stainless steel, or duplex shafts upon request. It provides a capacity range from 50 to 1000 GPM and pressures from 65 to 234 PSI, with a maximum working pressure of 180 to 315 PSI. The pump operates at speeds of 2900, 3000, 3500, and 3600 RPM. The specific model Dsg. SFP 50-42 EH has a rated capacity of 50 GPM, a flange size of 2 ½ x 1 ½ inches, and is UL listed. It delivers a rated net pressure range of 122 to 146 PSI and operates at an approximate speed of 3000 RPM with a maximum working pressure of 230 PSI.
