This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet. It utilizes a bronze impeller and a stainless steel shaft equipped with a bronze shaft sleeve. The dry shaft design prevents contact between the circulating fluid and the shaft, supporting a 125 PSI pressure rating. Internal sealing is provided by a mechanical seal with a ceramic seat and EPT rubber elements.
The assembly utilizes a 30 HP premium efficiency TEFC motor that operates at 3450 RPM, incorporates Aegis grounding, and is powered by a 200-230V, 3PH supply, resulting in a DOE PEI of 0.46. 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.
