This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller. The design utilizes a dry shaft assembly to prevent fluid contact, which allows for operation at 125 PSI without a wear ring. A bronze shaft sleeve protects the pump shaft and facilitates seal maintenance. The mechanical seal comprises a ceramic seat and EPT rubber elements to ensure fluid containment.
The assembly integrates a 5 HP premium efficiency TEFC motor operating at 1750 RPM, equipped with Aegis grounding, and powered by a 200-230V 3PH electrical supply, achieving a DOE PEI rating of 0.43. 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.
