This close-coupled end suction pump integrates a cast iron casing with a bronze impeller and a stainless steel shaft sleeve. The dry shaft design prevents contact between the circulating fluid and the shaft, protecting against corrosion. A mechanical seal utilizes a ceramic seat half and EPT rubber to maintain pressure integrity up to 250 PSI when equipped with a wear ring. This assembly incorporates self-sensing quadratic variable flow technology to manage hydraulic output.
This pump operates with a 20 HP premium efficiency TEFC motor at 1750 RPM, utilizing Aegis grounding on a 380-460V 3PH power supply with 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.
