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 and a dry shaft mechanical seal design, which prevents contact between the shaft and the circulating fluid. A ceramic seat and EPT rubber are used in the construction of the mechanical seal to maintain system integrity. The unit sustains 125 PSI operation without the use of a wear ring.
The system utilizes a 25 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding on a 200-230V / 3PH power supply, resulting in 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
