This base-mounted end suction pump incorporates a cast iron casing with integrally cast mounting feet and a bronze impeller. The pump utilizes a dry shaft design that prevents the circulating fluid from contacting the stainless steel shaft, which is covered by a replaceable bronze shaft sleeve. Sealing is managed by a silicon-carbide seat half with EPT components. The pump construction is rated for 125 PSI and allows for maintenance of the internal components without disturbing the system piping.
The unit is powered by a 20 HP premium efficiency ODP motor operating at 1750 RPM, integrating Aegis grounding and a 380-460V 3PH power supply. 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.
