This close-coupled end suction pump incorporates a cast iron casing, a bronze impeller, and a bronze shaft sleeve. The dry shaft design prevents contact between the shaft and the circulating fluid, reducing potential for corrosion. A mechanical seal utilizing a ceramic seat and EPT rubber provides containment, while the pump assembly is rated for 125 PSI operation and includes a wear ring.
The pump utilizes a 3 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding, a power supply of 380-460V / 3PH, and 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
