This close-coupled end suction pump is constructed with a cast iron casing, a bronze impeller, and a bronze shaft sleeve. It incorporates a dry shaft design that eliminates contact between the shaft and the circulating fluid, allowing the assembly to function at 125 PSI without a wear ring. The pump utilizes a mechanical seal comprised of a ceramic seat and EPT rubber. Integrated pressure tappings on suction and discharge connections allow for system monitoring.
Powered by a 50 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding, the unit runs on a 380-460V / 3PH power supply, yielding a DOE PEI of 0.46. 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.
