This base-mounted end suction pump utilizes a class 30 cast iron casing with center-line discharge for positive air venting and a hydraulically balanced bronze impeller. Its dry shaft design protects the stainless steel shaft by preventing contact with circulating fluid, and the assembly incorporates a replaceable bronze shaft sleeve for simplified seal maintenance. A mechanical seal with a ceramic seat and EPT rubber ensures integrity at pressures up to 125 PSI. The pump bearing housing contains permanently lubricated, sealed-for-life ball bearings, which allows for service without disturbing existing piping connections.
Powered by a 5 HP Premium Efficiency ODP motor operating at 1750 RPM, the assembly utilizes Aegis grounding and functions on 208V 3PH power with a DOE PEI rating of 0.44. The 'S' in the SFI series denotes Taco's advanced Self-Sensing technology, which eliminates remote sensors and field wiring by using internal mathematical algorithms to calculate system resistance and automate variable flow. The included VFD is configured with a fused disconnect without bypass and holds an enclosure NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
