This base-mounted end suction pump comprises a cast iron casing with a center-line discharge and a bronze impeller. The assembly utilizes a dry shaft design that prevents fluid contact with the stainless steel shaft, which is protected by a stainless steel sleeve. Sealing is provided by a ceramic seat and Viton rubber, supporting internal pressures up to 125 PSI. A bronze wear ring is integrated into the casing to maintain hydraulic performance.
The 25 HP premium efficiency TEFC motor operates at 3450 RPM and utilizes Aegis grounding, powered by 200-230V / 3PH electricity 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.
