This close-coupled end suction pump incorporates a cast iron casing with a bronze impeller and a bronze shaft sleeve. The design utilizes a dry shaft that eliminates contact between the circulating fluid and the pump shaft, rated for 125 PSI without a wear ring. The mechanical seal assembly comprises a ceramic seat half with EPT rubber components. Flush seal line taps facilitate filter installation to manage non-condensable particles, while integrated suction and discharge connections provide standard pressure tappings for system monitoring.
The 20 HP premium efficiency TEFC motor operates at 1750 RPM with Aegis grounding on a 380-460V / 3PH power supply. The 'S' in the SCI 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.
