This base-mounted end suction pump incorporates a cast iron casing with integrally cast mounting feet and a bronze impeller. The pump utilizes a stainless steel shaft protected by a replaceable bronze shaft sleeve. A dry shaft mechanical seal design integrates a ceramic seat and EPT rubber, accommodating system pressures up to 125 PSI.
The assembly utilizes a 7.5 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding, powered by 200-230V 3PH electrical supply, achieving a DOE PEI 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
