This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller, utilizing a dry shaft design that eliminates circulating fluid contact to protect the internal components. It integrates a stainless steel shaft sleeve for seal maintenance efficiency, while the mechanical seal assembly comprises a ceramic seat and EPT rubber. Engineered for systems operating up to 125 PSI without a wear ring, this pump facilitates consistent fluid transfer and includes standard pressure tappings on both the suction and discharge connections.
The pump operates with a 50 HP premium efficiency TEFC motor at 1750 RPM, integrating Aegis grounding for electrical protection, 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
