This base-mounted end suction pump is constructed with a class 30 cast iron casing and integrally cast mounting feet. The assembly utilizes a bronze impeller and a stainless steel shaft paired with a replaceable bronze shaft sleeve. Engineered with a dry shaft design to prevent circulating fluid from contacting the shaft, the unit maintains a mechanical seal comprising a ceramic seat and EPT elastomer, rated for 125 PSI.
The motor provides 7.5 HP with a premium efficiency TEFC enclosure operating at 1750 RPM, utilizing Aegis grounding on a 200-230V, 3PH power supply with a DOE PEI of 0.44. 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.
