This base-mounted end suction pump utilizes a cast iron casing with center-line discharge and integrally cast mounting feet. The assembly incorporates a bronze impeller and a stainless steel shaft with a replaceable bronze shaft sleeve. This pump integrates a dry shaft design to prevent contact between the circulating fluid and the shaft. The mechanical seal consists of ceramic seat halves and EPT rubber, rated for 125 PSI.
The 20 HP premium efficiency TEFC motor operates at 3450 RPM, includes Aegis grounding for 380-460V 3PH power, and carries a DOE PEI of 0.48. 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.
