This close-coupled end suction pump utilizes a cast iron casing with an integrated bronze impeller and a bronze shaft sleeve. Engineered with a dry shaft design, the unit limits fluid contact with the shaft, while flush seal line taps accommodate filter installation for protection against non-condensable particles. The mechanical seal incorporates a ceramic seat and EPT rubber, providing a pressure rating of 125 PSI without a wear ring. Pressure tappings are located on the suction and discharge connections to facilitate system monitoring.
The assembly operates with a 5 HP premium efficiency TEFC motor at 1750 RPM, integrates Aegis grounding for protection, and utilizes a 380-460V / 3PH power supply with 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
