This base-mounted end suction pump comprises a cast iron casing with a bronze impeller and a bronze shaft sleeve assembled over a stainless steel shaft. It incorporates a dry shaft design that isolates the shaft from circulating fluids and operates at a pressure rating of 125 PSI. The pump utilizes a mechanical seal constructed with a ceramic seat half and EPT rubber to prevent fluid leakage.
The assembly utilizes a 100 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis shaft grounding, powered by a 380-460V / 3PH 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.
