This end suction pump incorporates a cast iron casing with an integrally cast bronze impeller and a stainless steel shaft. A bronze shaft sleeve protects the shaft from circulating fluid within the dry shaft assembly, supporting operation up to 125 PSI. The mechanical seal utilizes ceramic and EPT components to maintain system integrity.
The pump operates with a 7.5 HP premium efficiency TEFC motor at 1750 RPM, which integrates Aegis grounding and utilizes a 380-460V 3PH power supply, resulting in a DOE PEI rating of 0.47. 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.
