This close-coupled end suction pump comprises a cast iron casing housing a bronze impeller and a bronze shaft sleeve. The dry shaft assembly prevents contact with the circulating fluid, while the mechanical seal utilizes a ceramic seat and EPT rubber. This assembly is engineered to withstand pressures up to 125 PSI without a wear ring. Integrating flush seal line taps allows for filter installation, and suction and discharge connections are equipped with pressure tappings to facilitate system monitoring.
Powered by a 5 HP premium efficiency TEFC motor, this unit operates at 1750 RPM with Aegis grounding and a 200-230V 3PH power supply, yielding a DOE PEI rating 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.
