This close-coupled end suction pump comprises a cast iron casing with a bronze impeller and a bronze shaft sleeve. It utilizes a dry shaft design that prevents contact between the circulating fluid and the pump shaft, thereby reducing corrosion risks. The mechanical seal assembly incorporates a ceramic seat half and EPT rubber, providing a pressure rating of 125 PSI. Internal pressure tappings on the suction and discharge connections allow for monitoring system pressure, while flush seal line taps accommodate the installation of filtration to protect the seal from non-condensable particles.
Operating with a 20 HP premium efficiency TEFC motor at 1750 RPM, the assembly utilizes Aegis grounding and runs on 380-460V 3PH power, with a DOE PEI of 0.46. 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 an electro-mechanical bypass with a main disconnect and 5kA SCCR, holding an enclosure NEMA Type 3R / IP 64 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
