This close-coupled end suction pump utilizes a cast iron casing with a bronze impeller and a bronze shaft sleeve. The design integrates a dry shaft to prevent contact between the circulating fluid and the shaft, supporting an operational pressure rating of 125 PSI. A mechanical seal assembly incorporates a ceramic seat half and EPT rubber to maintain fluid containment. Flush seal line taps are provided to allow for the installation of external filtration, while the casing provides pressure tappings on both the suction and discharge connections to facilitate system monitoring.
This assembly utilizes a 3 HP Premium Efficiency ODP motor operating at 1750 RPM with Aegis grounding on a 200-230V 3PH power supply, resulting in a DOE PEI rating of 0.45. 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.
