This close-coupled end suction pump comprises a cast iron casing and a bronze impeller to facilitate water circulation. The assembly integrates a dry shaft design that prevents circulating fluid from contacting the shaft, which eliminates the requirement for specialized corrosion-resistant shaft materials. A bronze shaft sleeve allows for simplified maintenance in the field. The mechanical seal utilizes a silicon-carbide seat half paired with EPT rubber, while the unit maintains a pressure capacity of 125 PSI. Flush seal line taps permit the installation of a filter for protection against non-condensable particles, and the casing includes pressure tappings on suction and discharge connections.
The 2 HP premium efficiency ODP motor operates at 1750 RPM, utilizes Aegis grounding, functions with 380-460V / 3PH power, and carries a DOE PEI of 0.43. 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
