This close-coupled end suction pump utilizes a cast iron casing and a bronze impeller to facilitate fluid transfer. The assembly incorporates a bronze shaft sleeve alongside a dry shaft design that eliminates contact between the circulating fluid and the shaft. A mechanical seal serves the system, constructed with a ceramic seat half and EPT rubber, providing a pressure rating of 125 PSI without a wear ring.
This unit operates with a 25 HP premium efficiency TEFC motor at 1750 RPM, which integrates Aegis grounding, operating on 380-460V / 3PH power with a DOE PEI rating of 0.48. 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.
