This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a bronze shaft sleeve on a stainless steel shaft. The assembly incorporates a dry shaft design that isolates the shaft from circulating fluids and carries a 125 PSI pressure rating. Mechanical sealing consists of a silicon-carbide seat with EPT rubber components, maintaining operational integrity. Center-line discharge allows for efficient air venting, while integrally cast mounting feet provide structural support.
Power is provided by a 20 HP premium efficiency TEFC motor operating at 1750 RPM, equipped with Aegis grounding, and energized by a 200-230V / 3PH power supply with 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
