This close-coupled end suction pump integrates a cast iron casing, bronze impeller, and bronze shaft sleeve. The dry shaft design prevents contact between circulating fluid and the pump shaft, while the mechanical seal utilizes a ceramic seat half and EPT rubber. The unit accommodates operating pressures up to 125 PSI and provides pressure tappings on the suction and discharge connections for monitoring. Flush seal line taps allow for the installation of an external filter to protect the seal from non-condensable particles.
The 25 HP premium efficiency ODP motor operates at 3450 RPM with Aegis grounding on a 200-230V / 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
