The SFP 500-31 EM centrifugal fire pump is designed for end suction applications with a top centerline discharge. It features a foot-supported casing and a back pullout design for easy maintenance. The pump incorporates a self-venting design to prevent air lock and ensure smooth operation. Its efficiently designed impeller enhances performance efficiency, while the frame-mounted design ensures stability and durability, making it suitable for retrofitting in spaces with limited room. The pump is constructed with heavy-duty materials including cast iron or ductile iron casing, and offers options for bronze or duplex impellers and alloy steel, stainless steel, or duplex shafts upon request. It has a capacity range from 50 to 1000 GPM, operating at pressures from 65 to 234 PSI with a maximum working pressure of 180 to 315 PSI. Available in speeds of 2900, 3000, 3500, and 3600 RPM, it meets stringent industry standards with 100% hydrostatic and performance testing.
