This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller to facilitate fluid transfer. The assembly utilizes a bronze shaft sleeve and a mechanical seal constructed with a ceramic seat and EPT rubber to provide sealing. Designed with a dry shaft configuration rated for 125 PSI, the pump prevents contact between the shaft and the circulating fluid. Pressure tappings are integrated into the suction and discharge connections to support system monitoring.
This assembly utilizes a 20 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis shaft grounding, powered by 230V 3PH electricity, and maintains a DOE PEI rating 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.
