This base-mounted end suction pump integrates a cast iron casing with a bronze impeller and a stainless steel shaft. The assembly utilizes a replaceable bronze shaft sleeve and a dry shaft design that eliminates contact between the circulating fluid and the shaft. A mechanical seal constructed with ceramic and EPT materials provides fluid containment for systems operating up to 125 PSI.
The 7.5 HP Premium Efficiency TEFC motor operates at 1750 RPM with Aegis grounding on a 200-230V 3PH power supply, achieving 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.
