This close-coupled end suction pump incorporates a cast iron casing with a bronze impeller and a bronze shaft sleeve. It utilizes a mechanical seal constructed with a ceramic seat and EPT rubber. The assembly integrates a dry shaft design that eliminates contact between the circulating fluid and the pump shaft, supporting pressure ratings up to 125 PSI without a wear ring. Pressure tappings are provided on both suction and discharge connections to facilitate system monitoring.
The pump operates with a 5 HP Premium Efficiency TEFC motor at 1750 RPM, which integrates Aegis Grounding and supports a 380-460V / 3PH power supply, resulting in a DOE PEI rating 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
