This base-mounted end suction pump incorporates a cast iron casing with an integrally cast center-line discharge and a bronze impeller. The pump assembly utilizes a stainless steel shaft protected by a replaceable bronze shaft sleeve, which prevents contact with the circulating fluid through a dry shaft design. Mechanical sealing is provided by a ceramic and EPT seal arrangement, rated for a maximum pressure of 125 PSI.
Powered by a 7.5 HP premium efficiency ODP motor, the unit operates at 1750 RPM, integrates Aegis grounding, and accepts 380-460V / 3PH power input, achieving 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.
