This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller to facilitate liquid transfer. The assembly utilizes a bronze shaft sleeve and a dry shaft design that eliminates contact between the circulating fluid and the pump shaft, supporting pressure ratings up to 125 PSI without a wear ring. A mechanical seal utilizes a ceramic seat and EPT rubber to maintain system integrity. This configuration includes flush seal line taps to facilitate the installation of an optional filter for protection against non-condensable particles. Integrated pressure tappings on suction and discharge connections allow for monitoring during operation.
This pump integrates a 20 HP premium efficiency TEFC motor that operates at 3450 RPM and utilizes Aegis grounding, powered by a 380-460V 3PH supply with 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 Type 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
