This close-coupled end suction pump is constructed with a cast iron casing and a bronze impeller to facilitate efficient fluid transfer. The assembly incorporates a dry shaft design that eliminates contact between the shaft and the circulating fluid, protecting the component against corrosion. A stainless steel shaft sleeve aids in field maintenance, while the mechanical seal utilizes a ceramic seat half with EPT rubber elements. Engineered to operate at 125 PSI without a wear ring, the unit provides performance for cooling water transfer and pressure boosting systems. Pressure tappings are integrated into the suction and discharge connections to assist with monitoring system conditions.
Powered by a 50 HP Premium Efficiency TEFC 1750 RPM motor with Aegis grounding, the assembly operates on 380-460V / 3PH power and holds 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 with bypass and holds an enclosure NEMA 3R / IP 64 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
