This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a bronze shaft sleeve to protect the shaft from contact with the circulating fluid, adhering to a dry shaft design rated for 125 PSI. The mechanical seal assembly comprises a ceramic seat and EPT rubber components to ensure fluid containment. This assembly permits service of the pump internals without disturbing the existing system piping connections, while integrated suction and discharge pressure tappings allow for monitoring of hydraulic performance.
This unit operates with a 20 HP premium efficiency TEFC motor at 1750 RPM, which integrates Aegis grounding, powered by 380-460V 3PH input, and maintains a DOE PEI rating 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
