This close-coupled end suction pump incorporates a cast iron casing with a bronze impeller and bronze shaft sleeve. The dry shaft design prevents contact between the shaft and circulating fluid. The mechanical seal utilizes a ceramic seat half and EPT rubber. This assembly supports a 125 PSI rating and integrates flush seal line taps to allow for filter installation. Suction and discharge pressure tappings are provided for monitoring.
The unit operates with a 3 HP premium efficiency TEFC motor at 1750 RPM, utilizing Aegis grounding and a 200-240V 1PH power supply with a DOE PEI rating of 0.45. 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.
