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 through a dry shaft design, which isolates the rotating assembly from the circulating fluid. The mechanical seal utilizes a ceramic seat and EPT rubber to provide operation up to 125 PSI.
Power is supplied by a 3 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis shaft grounding, rated for 380-460V / 3PH power, resulting in a DOE PEI of 0.48. 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.
