This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. A bronze shaft sleeve protects the shaft from direct contact with circulating fluid in a dry shaft design that sustains a pressure rating of 125 PSI. The mechanical seal assembly comprises a ceramic seat and EPT rubber components to ensure fluid containment.
This assembly operates with a 20 HP Premium Efficiency TEFC motor at 1750 RPM, incorporating Aegis grounding for the 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
