This base-mounted end suction pump incorporates a cast iron casing with a stainless steel impeller and a stainless steel shaft. It integrates a replaceable bronze shaft sleeve and a dry shaft design that prevents the circulating fluid from contacting the shaft. The unit maintains a pressure rating of 125 PSI and utilizes a mechanical seal comprised of ceramic seat halves and EPT rubber.
The assembly utilizes a 125 HP premium efficiency TEFC motor operating at 1750 RPM, which integrates Aegis grounding and functions on 575-600V 3PH power. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
