This base-mounted end suction pump comprises a cast iron casing with an integrally cast bronze impeller and a stainless steel shaft. A bronze shaft sleeve protects the shaft from contact with the circulating fluid, while the dry shaft mechanical seal utilizes a ceramic seat and EPT rubber components to operate at system pressures up to 125 PSI.
Powered by a 25 HP Premium Efficiency TEFC motor, this assembly operates at 1750 RPM and incorporates Aegis grounding, a 380-460V / 3PH power supply, and carries 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.
