This base-mounted end suction pump incorporates a cast iron casing and a bronze impeller. It utilizes a stainless steel shaft paired with a bronze shaft sleeve to maintain structural integrity. The dry shaft design prevents contact between the circulating fluid and the shaft, supporting an operating pressure of 125 PSI. A mechanical seal assembly utilizing a ceramic seat and EPT rubber isolates the internal components.
The 20 HP premium efficiency TEFC motor operates at 3450 RPM and integrates Aegis grounding on a 200-230V 3PH power supply, yielding a DOE PEI rating of 0.47. 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.
