This base-mounted end suction pump utilizes a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly integrates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft. A replaceable bronze shaft sleeve protects the shaft, while a mechanical seal with a ceramic seat and EPT rubber components maintains fluid integrity. This pump maintains a 125 PSI rating and provides parallel pumping and multi-pump control capabilities.
Powered by a 30 HP premium efficiency TEFC motor, the unit operates at 1750 RPM and integrates Aegis grounding, utilizing a 380-460V / 3PH supply with a DOE PEI rating of 0.46. 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.
