This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a center-line discharge. It utilizes a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. The design incorporates a dry shaft construction to prevent contact with circulating fluid and includes a ceramic mechanical seal with EPT elastomers. This assembly provides a pressure rating of 125 PSI and integrates a bronze wear ring.
The pump utilizes a 25 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis shaft grounding, powered by a 380-460V 3PH supply, and maintains a DOE PEI rating 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.
