This base-mounted end suction pump comprises a class 30 cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly utilizes a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft. Protection is provided by a bronze shaft sleeve and a mechanical seal constructed with a ceramic seat and EPT rubber. The internal design supports a 125 PSI pressure rating and incorporates a replaceable bronze wear ring.
This pump operates with a 40 HP premium efficiency TEFC motor at 1750 RPM, utilizing Aegis grounding on a 380-460V, 3PH power supply. 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.
