This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. It integrates a bronze shaft sleeve over a stainless steel shaft, utilizing a dry shaft design that prevents the circulating fluid from contacting the internal shaft. The mechanical seal assembly incorporates ceramic and EPT components, providing a pressure rating of 125 PSI.
The 7.5 HP Premium Efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, powered by a 200-230V 3PH supply with a DOE PEI rating 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
