This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The design incorporates a dry shaft and a stainless steel shaft equipped with a replaceable bronze shaft sleeve. This pump utilizes a mechanical seal composed of an EPT rubber component and a ceramic seat half, supporting a pressure rating of 125 PSI. It includes a wear ring within the volute casing.
This assembly utilizes a 7.5 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding, powered by a 200-230V, 3PH electrical supply, with 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
