This base-mounted end suction pump incorporates a cast iron casing and a bronze impeller. The unit utilizes a stainless steel shaft equipped with a replaceable bronze shaft sleeve and a dry shaft design that prevents circulating fluid from contacting the shaft. Sealing is achieved via a mechanical seal with ceramic seat halves and EPT rubber, providing a pressure rating of 125 PSI. This construction allows for maintenance and servicing without removing system piping.
This assembly utilizes a 7.5 HP Premium Efficiency TEFC motor operating at 3450 RPM with Aegis Grounding at 380-460V / 3PH power, resulting in 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.
