This base-mounted end suction pump comprises a cast iron casing with an integrated bronze impeller and a bronze shaft sleeve positioned over a stainless steel shaft. The assembly utilizes a dry shaft mechanical design to prevent circulating fluid from contacting the internal shaft, while the seal consists of a ceramic seat and EPT rubber. This configuration maintains a maximum pressure rating of 125 PSI and incorporates a wear ring to support consistent hydraulic performance.
The 25 HP premium efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding, powered by a 200-230V / 3PH electrical 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.
