This base-mounted end suction pump integrates a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a dry shaft design that prevents contact between the shaft and circulating fluid. A bronze shaft sleeve protects the shaft from corrosion. The assembly utilizes an EPT rubber and ceramic mechanical seal rated for 125 PSI.
Powered by a 50 HP Premium Efficiency TEFC motor, this assembly operates at 1750 RPM. It integrates Aegis grounding, operates on 380-460V 3PH power, and achieves 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
