This base-mounted end suction pump comprises a class 30 cast iron casing with integrally cast mounting feet. The hydraulic assembly utilizes a bronze impeller and a stainless steel shaft covered by a replaceable bronze shaft sleeve. This mechanical seal design integrates an EPT rubber component with a ceramic seat half to manage fluids within a 125 PSI operating limit. The unit follows a dry shaft construction, which prevents circulating fluid from making contact with the pump shaft to mitigate corrosion.
The 25 HP premium efficiency TEFC motor operates at 1750 RPM, includes Aegis grounding, and accepts 380-460V / 3PH power 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.
