This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller. The design utilizes a dry shaft configuration that isolates the shaft from the circulating fluid, providing protection at a pressure rating of 125 PSI without the use of a wear ring. A bronze shaft sleeve facilitates maintenance, while the mechanical seal is constructed with a ceramic seat and EPT rubber components. The assembly integrates flush seal line taps and pressure tappings on both the suction and discharge connections to monitor system performance.
The assembly utilizes a 20 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding, configured for a 380-460V 3PH power supply, and carries 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.
