This base-mounted end suction pump comprises a cast iron casing with an integrally cast bronze impeller and a stainless steel shaft. It incorporates a replaceable bronze shaft sleeve and a dry shaft design that prevents contact between the circulating fluid and the shaft. The mechanical seal assembly utilizes a ceramic seat with EPT rubber, providing a pressure rating of 125 PSI. This configuration ensures hydraulic stability and facilitates maintenance by allowing the seal and bearing housing to be serviced without disturbing the surrounding system piping.
Powered by a 40 HP premium efficiency TEFC motor, the assembly operates at 3450 RPM and includes Aegis grounding for protection against electrical discharge, utilizing a 380-460V / 3PH power supply with a DOE PEI rating of 0.47. 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.
