This base-mounted end suction pump comprises a cast iron casing with center-line discharge and an integrally cast mounting foot. The assembly utilizes a bronze impeller and a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft. A replaceable bronze shaft sleeve protects the shaft from wear, while the mechanical seal incorporates a ceramic seat with EPT elastomers. This configuration supports a maximum pressure rating of 125 PSI.
The pump operates with a 3 HP Premium Efficiency ODP motor at 1750 RPM, utilizing Aegis shaft grounding, for 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
