This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller. The pump utilizes a bronze shaft sleeve and a dry shaft design that eliminates contact between the fluid and the pump shaft, supporting a 125 PSI pressure rating without a wear ring. A mechanical seal is constructed with a ceramic seat and EPT rubber to manage fluid containment. The assembly includes flush seal line taps to allow for filter installation and integrates pressure tappings on the suction and discharge connections to monitor system performance.
The assembly operates with a 5 HP Premium Efficiency TEFC motor at 1750 RPM, utilizing Aegis grounding and a 380-460V / 3PH power supply, achieving 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.
