This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly utilizes a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. For fluid containment, the unit incorporates a mechanical seal assembly consisting of a ceramic seat and EPT rubber. This pump construction maintains a 125 PSI pressure rating.
The pump operates with a 7.5 HP premium efficiency TEFC motor at 1750 RPM, integrating Aegis grounding and a power supply of 380-460V / 3PH, resulting in a DOE PEI rating of 0.44. 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.
