This base-mounted end suction pump comprises a cast iron casing with an integrally cast bronze impeller and bronze shaft sleeve on a stainless steel shaft. The assembly incorporates a dry shaft design rated for 125 PSI and utilizes a mechanical seal constructed with a ceramic seat half and EPT rubber. Suction and discharge connections integrate pressure tappings for system monitoring.
This assembly utilizes a 7.5 HP premium efficiency TEFC motor operating at 1750 RPM, Aegis grounding, and a 200-230V 3PH power supply, achieving a DOE PEI 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.
