This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. The assembly incorporates a bronze shaft sleeve and a silicon-carbide mechanical seal seat with EPT rubber components. This dry shaft design prevents contact between the circulating fluid and the shaft, supporting a pressure rating of 125 PSI without a wear ring.
The unit operates with a 40 HP Premium Efficiency ODP motor at 1750 RPM with Aegis grounding on 380-460V 3PH power. 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
