This close-coupled end suction pump utilizes a cast iron casing and a bronze impeller to facilitate fluid transfer. The assembly integrates a bronze shaft sleeve and a dry shaft design that eliminates contact between the circulating fluid and the pump shaft. A mechanical seal constructed with a ceramic seat half and EPT rubber components maintains system integrity at a pressure rating of 125 PSI. Pressure tappings on the suction and discharge connections allow for monitoring, while flush seal line taps accommodate an optional filter for protection against non-condensable particles.
The 5 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and receives power via a 380-460V 3PH 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
