This base-mounted end suction pump incorporates a cast iron casing with a bronze impeller and a stainless steel shaft. A bronze shaft sleeve protects the shaft components through a dry shaft design that prevents circulating fluid contact. The pump assembly integrates a ceramic and EPT mechanical seal with a 125 PSI operational capacity.
The motor operates at 7.5 HP with a premium efficiency rating and a TEFC enclosure at 1750 RPM, utilizing Aegis grounding and a 380-460V / 3PH power supply, resulting in a DOE PEI of 0.45. 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.
