This base-mounted end suction pump incorporates a cast iron casing with a stainless steel impeller and a stainless steel shaft protected by a bronze shaft sleeve. The dry shaft design prevents fluid contact with the rotating shaft, operating at pressures up to 125 PSI without a wear ring. A mechanical seal integrates silicon-carbide seat material with EPT rubber components to maintain system integrity.
The motor utilizes 7.5 HP, premium efficiency, TEFC, 1750 RPM, Aegis grounding, and operates on 380-460V / 3PH power with a DOE PEI rating of 0.45. 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.
