This close-coupled end suction pump integrates a cast iron casing with a bronze impeller and a bronze shaft sleeve. The dry shaft design eliminates fluid contact with the pump shaft and supports 125 PSI pressure without a wear ring. Mechanical sealing consists of a ceramic seat and EPT rubber. This assembly incorporates flush seal line taps, which allow for the installation of an optional filter to protect components from non-condensable particles. Integrated pressure tappings on the suction and discharge connections permit monitoring of hydraulic performance in open systems.
This unit utilizes a 3 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding on a 200-230V 3PH power supply, yielding 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 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.
