This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a bronze shaft sleeve positioned over a stainless steel shaft. The assembly incorporates a dry shaft design that prevents contact between the circulating fluid and the shaft, maintaining pressure ratings of 125 PSI. Fluid sealing is managed through a ceramic and EPT mechanical seal arrangement. The pump construction supports maintenance without disturbing existing system piping, while integrally cast mounting feet provide structural stability during operation.
Operating at 30 HP with a premium efficiency TEFC motor at 3450 RPM, the assembly utilizes Aegis grounding and operates on a 380-460V, 3PH power 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.
