Series SSF-22U small, stainless steel circulator pumps are used for domestic, potable water. The SSF-22U pumps are permanently-lubricated with a 1/25 HP, 2940 RPM, 115v, single phase motor. Series SSF pumps are reliable, in-line wet rotor circulator pumps. The maintenance-free system, with a self-cleaning particle shield, and DuraGlide bearing system protects the shaft and bearings from system start-up debris. A Red Fox motor offers high starting torque, and the stabilized, heat-resistant, non-metallic impeller with a closed design improves overall operating efficiency. Mounting hardware and flange gaskets are included. Flanges are available separately.
