This close-coupled end suction pump comprises a cast iron casing with a bronze impeller and a bronze shaft sleeve. Engineered with a dry shaft design, the assembly prevents contact between the circulating fluid and the pump shaft to maintain structural integrity. The mechanical seal assembly utilizes a ceramic seat and EPT rubber, providing a 125 PSI pressure rating with a wear ring. Pressure tappings are integrated into the suction and discharge connections, and flush seal line taps allow for the installation of a filter to protect the seal from non-condensable particles in open systems.
The 25 HP premium efficiency TEFC motor operates at 3450 RPM, incorporates Aegis grounding, and utilizes a 380-460V 3PH power supply, resulting in a DOE PEI rating of 0.48. 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.
