This close-coupled end suction pump utilizes a cast iron casing and a bronze impeller to facilitate fluid transfer. The assembly incorporates a dry shaft design with a bronze shaft sleeve, which prevents contact between the shaft and the circulating fluid. Sealing is managed by a mechanical design utilizing a ceramic seat half and EPT rubber, supporting operation at pressures up to 125 PSI without a wear ring. Pressure tappings are integrated into the suction and discharge connections to allow for monitoring. The unit also integrates flush seal line taps to permit the installation of a filter for protection against non-condensable particles.
This assembly operates with a 7.5 HP Premium Efficiency TEFC motor at 1750 RPM, which integrates Aegis grounding and functions on a 380-460V / 3PH power supply, yielding a DOE PEI rating of 0.47. 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.
