This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller to facilitate liquid transfer. The mechanical design utilizes a dry shaft that prevents contact between the circulating fluid and the shaft, which is supplemented by a bronze shaft sleeve. Sealing is accomplished via a ceramic seat half and EPT rubber, allowing for operation at a pressure of 125 PSI without a wear ring. This assembly integrates pressure tappings on the suction and discharge connections to provide access for system monitoring.
Powered by a 7.5 HP Premium Efficiency ODP motor operating at 1750 RPM, the unit utilizes Aegis Grounding and accepts a 380-460V, 3PH power supply, resulting in 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
