This close-coupled end suction pump incorporates a cast iron casing with a bronze impeller and a bronze shaft sleeve. The assembly utilizes a dry shaft design that isolates the pump shaft from the circulating fluid, while the mechanical seal features a ceramic seat with EPT rubber elements. Pressure tappings are located on the suction and discharge connections for monitoring system conditions. The pump architecture includes flush seal line taps intended for the installation of an external filter to mitigate the presence of non-condensable particles in the fluid stream.
The 7.5 HP premium efficiency TEFC motor operates at 1750 RPM with Aegis grounding and a 208V 3PH power supply. 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.
