This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller to manage fluid movement. A bronze shaft sleeve protects the pump internals, while the dry shaft mechanical seal design utilizes a ceramic seat half and EPT rubber, rated for a maximum pressure of 125 PSI. These components work in conjunction to facilitate circulation in heating and cooling systems while maintaining internal integrity through flush seal line taps and standard pressure tappings on suction and discharge connections.
The assembly utilizes a 3 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding, powered by a 380-460V / 3PH electrical 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.
