This base-mounted end suction pump utilizes a class 30 cast iron casing with integrally cast mounting feet and a bronze impeller dynamically balanced to ANSI Grade G6.3. The assembly integrates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. For fluid containment, the pump incorporates a mechanical seal constructed with ceramic seat halves and EPT elastomers. The pump operates at a pressure rating of 125 PSI without a wear ring and provides center-line discharge for positive air venting.
Powered by a 15 HP premium efficiency TEFC motor operating at 3450 RPM, the assembly incorporates an Aegis grounding ring and utilizes 380-460V 3PH power with a DOE PEI rating of 0.45. 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.
