This base-mounted end suction pump utilizes a cast iron casing with integrally cast mounting feet and a bronze impeller. The design incorporates a dry shaft construction to prevent contact between the circulating fluid and the stainless steel shaft and shaft sleeve. Hydraulic pressure capacity is rated at 125 PSI, supported by a bronze wear ring. The mechanical seal assembly comprises a ceramic seat with EPT rubber components.
The pump operates with a 20 HP Premium Efficiency TEFC motor at 1750 RPM, integrated with Aegis shaft 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
