This close-coupled end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly integrates a bronze shaft sleeve within a dry shaft design that eliminates contact between the pump shaft and the circulating fluid. Rated for 125 PSI operation without a wear ring, the unit incorporates a mechanical seal comprising a ceramic seat and EPT rubber. Suction and discharge connections include pressure tappings for system monitoring.
The motor operates at 7.5 HP with Premium Efficiency, utilizes a TEFC enclosure, maintains 3450 RPM, includes Aegis Grounding, and functions on a 200-230V, 3PH power supply, yielding 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.
