This base-mounted end suction pump comprises a cast iron casing with a center-line discharge and integrally cast mounting feet. The assembly utilizes a stainless steel impeller and a stainless steel shaft protected by a bronze shaft sleeve. This mechanical design incorporates a dry shaft configuration and a mechanical seal assembly composed of tungsten carbide seat halves with Viton rubber components. Rated for 125 PSI operation, the pump incorporates a wear ring to support consistent hydraulic performance.
Powered by a 40 HP premium efficiency TEFC motor operating at 1750 RPM, the system includes Aegis shaft grounding and operates on 200-230V 3PH power. 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.
