This base-mounted end suction pump utilizes 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, maintaining an operational pressure rating of 125 PSI. The assembly integrates a ceramic and EPT mechanical seal to facilitate fluid containment within the housing.
The pump operates with a 3 HP premium efficiency ODP motor at 1750 RPM, integrating Aegis grounding and a 200-230V 3PH power supply, resulting in a DOE PEI rating of 0.45. 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
