This base-mounted end suction pump comprises a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a dry shaft design that prevents contact between the circulating fluid and the shaft, which utilizes a bronze shaft sleeve. The mechanical seal assembly consists of a ceramic seat with EPT rubber components, providing a pressure rating of 125 PSI without a wear ring. This configuration allows for servicing without removing the surrounding system piping.
The 20 HP premium efficiency TEFC motor operates at 3450 RPM and includes Aegis grounding, accepting 380-460V 3PH power, 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
