This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. It integrates a stainless steel shaft with a bronze shaft sleeve. The dry shaft design prevents contact between the circulating fluid and the shaft, supporting a 125 PSI pressure rating. A wear ring is included, and the mechanical seal utilizes a ceramic seat with EPT rubber.
The assembly utilizes a 7.5 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis grounding, powered by 200-230V / 3PH electricity, and carries a DOE PEI of 0.44. 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.
