This close-coupled end suction pump is constructed with a cast iron casing, a bronze impeller, and a bronze shaft sleeve. The assembly utilizes a dry shaft design that eliminates fluid contact with the pump shaft. Internal sealing is provided by a mechanical seal incorporating a ceramic seat half and EPT rubber. This configuration maintains a pressure rating of 125 PSI without a wear ring.
The assembly integrates a 7.5 HP Premium Efficiency TEFC motor operating at 1750 RPM, equipped with Aegis grounding for a 380-460V / 3PH power supply, resulting in a DOE PEI 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.
