This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The design integrates a stainless steel shaft paired with a bronze shaft sleeve to protect internal components from the circulating fluid. A dry shaft configuration provides isolation from the fluid, while the assembly incorporates a mechanical seal constructed with a ceramic seat and EPT rubber. This pump operates at a pressure rating of 125 PSI without a wear ring.
This unit utilizes a 7.5 HP Premium Efficiency TEFC motor operating at 3450 RPM with Aegis grounding, powered by 380-460V 3PH electrical input, and maintains a DOE PEI rating of 0.47. 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.
