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 is constructed with a dry shaft design, which protects the pump shaft by preventing contact with the circulating fluid. The mechanical seal consists of a ceramic seat with EPT rubber, providing a pressure rating of 125 PSI without a wear ring. Pressure tappings are integrated into the suction and discharge connections to allow for system monitoring.
The 20 HP Premium Efficiency ODP motor operates at 3450 RPM and integrates Aegis grounding, powered by a 380-460V, 3PH supply, with a DOE PEI rating 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 drive fusing, holding an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
