This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a bronze shaft sleeve to isolate the shaft from circulating fluid. The mechanical seal assembly utilizes a ceramic seat and EPT rubber, providing a 125 PSI capacity. This dry shaft design prevents contact between the system fluid and the shaft.
The 30 HP Premium Efficiency TEFC motor operates at 1750 RPM with Aegis grounding, drawing 380-460V / 3PH power, and achieves a DOE PEI 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.
