This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. The assembly incorporates a bronze shaft sleeve as part of a dry shaft design that prevents fluid contact with the internal shaft. It is engineered with a mechanical seal comprising a ceramic seat and EPT rubber, rated for a maximum pressure of 125 PSI.
The 25 HP premium efficiency TEFC motor operates at 3450 RPM and incorporates Aegis grounding, powered by 380-460V / 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.
