This close-coupled end suction pump integrates a cast iron casing with a bronze impeller and a bronze shaft sleeve. It utilizes a dry shaft design that eliminates contact between the shaft and the circulating fluid, supporting operation at 125 PSI without a wear ring. The assembly includes a mechanical seal with a ceramic seat half and EPT rubber components to facilitate fluid containment. Flush seal line taps are provided to allow the installation of a filter, while standard pressure tappings on the suction and discharge connections enable system monitoring.
This assembly utilizes a 20 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding and a 380-460V / 3PH power supply, yielding 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
