This base-mounted end suction pump consists of a cast iron casing with an integrated bronze impeller and a stainless steel shaft covered by a bronze shaft sleeve. The dry shaft design prevents contact between the circulating fluid and the shaft, maintaining a pressure rating of 125 PSI with a wear ring. A mechanical seal using ceramic and EPT materials provides isolation during operation. The unit incorporates a centerline discharge design to facilitate air venting and simplified maintenance.
The 5 HP Premium Efficiency TEFC motor operates at 1750 RPM and utilizes Aegis grounding, powered by a 200-230V 3PH supply with a DOE PEI rating of 0.47. 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.
