This close-coupled end suction pump incorporates a cast iron casing with a bronze impeller and a bronze shaft sleeve. The dry shaft design eliminates contact between the circulating fluid and the shaft, which facilitates seal maintenance via a slip-on sleeve. It utilizes a silicon-carbide mechanical seal seat with EPT rubber. The assembly provides 125 PSI operation and integrates flush seal line taps with pressure tappings on both the suction and discharge connections.
The 7.5 HP premium efficiency ODP motor operates at 1750 RPM, incorporates Aegis grounding, and utilizes a 380-460V 3PH supply, achieving a DOE PEI 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
