This close-coupled end suction pump is constructed with a cast iron casing and a bronze impeller to facilitate water transfer. The assembly incorporates a bronze shaft sleeve and a dry shaft design that isolates the pump shaft from contact with the circulating fluid. A mechanical seal utilizes a ceramic seat and EPT rubber to provide a pressure rating of 125 PSI without a wear ring. Flush seal line taps allow for the installation of an optional filter to protect against non-condensable particles.
The 7.5 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, utilizing a 200-230V / 3PH power supply with a DOE PEI 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.
