This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller to facilitate fluid transfer. The assembly integrates a bronze shaft sleeve with a mechanical seal utilizing a ceramic seat and EPT rubber to prevent fluid contact with the internal shaft. Designed with a dry shaft construction, the unit maintains a maximum pressure rating of 125 PSI without a wear ring. The construction provides flush seal line taps to allow for the installation of an external filter, and pressure tappings remain available on the suction and discharge connections for monitoring system performance.
The pump operates with a 5 HP Premium Efficiency TEFC motor at 1750 RPM, utilizing Aegis grounding and a power supply of 380-460V 3PH, resulting in a DOE PEI rating of 0.43. 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.
