This close-coupled end suction pump utilizes a cast iron casing and a bronze impeller to facilitate fluid transfer. The assembly integrates a bronze shaft sleeve and a dry shaft design, which protects the pump shaft from contact with the circulating fluid. A mechanical seal with a ceramic seat half and EPT rubber ensures containment at pressures up to 125 PSI, while the inclusion of a wear ring maintains hydraulic efficiency. Flush seal line taps allow for the installation of a filter, and standard pressure tappings on the suction and discharge connections permit monitoring of system conditions.
The 3 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and receives power from a 200-230V 3PH supply, resulting in a DOE PEI of 0.45. 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.
