This base-mounted end suction pump is constructed with a cast iron casing and a stainless steel (NSF61) impeller. The assembly integrates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft. A bronze shaft sleeve protects the shaft, while a ceramic and EPT mechanical seal manages pressure up to 125 PSI. Designed for hydraulic balance, the pump facilitates fluid transfer in single-stage centrifugal applications.
Powered by a 7.5 HP premium efficiency TEFC motor operating at 3450 RPM, the assembly utilizes Aegis grounding on a 380-460V 3PH power supply, resulting in a DOE PEI rating of 0.43. 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.
