This close-coupled end suction pump incorporates 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 shaft, which accommodates pressures up to 125 PSI without a wear ring. Mechanical sealing is provided by a ceramic seat half and EPT rubber. The construction provides flush seal line taps for the installation of an optional filter and includes pressure tappings on suction and discharge connections to facilitate system monitoring.
The 7.5 HP premium efficiency TEFC motor operates at 1750 RPM, utilizes Aegis grounding, and is powered by 380-460V / 3PH current. 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.
