This base-mounted end suction pump comprises a cast iron casing with a bronze impeller and a stainless steel shaft. It utilizes a replaceable bronze shaft sleeve to facilitate maintenance and an EPT rubber and ceramic mechanical seal. The dry shaft design prevents contact between the circulating fluid and the shaft, maintaining an operating pressure rating of 125 PSI.
Powered by a 40 HP Premium Efficiency TEFC motor operating at 1750 RPM, the assembly incorporates Aegis Grounding and supports a 380-460V / 3PH power supply, resulting in 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.
