This base-mounted end suction pump integrates a cast iron casing with a bronze impeller and a stainless steel shaft. A bronze shaft sleeve protects the internal components through a dry shaft design that eliminates contact between the circulating fluid and the shaft. The unit incorporates a mechanical seal with a ceramic seat and EPT rubber, rated for 125 PSI operation.
Powered by a 3 HP premium efficiency TEFC motor, the assembly operates at 1750 RPM and utilizes Aegis grounding on a 200-230V / 3PH power supply, resulting in 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.
