This close-coupled end suction pump is constructed with a cast iron casing and a bronze impeller. The dry shaft design prevents contact between the circulating fluid and the pump shaft, which eliminates the need for corrosion-resistant shaft materials and incorporates a bronze shaft sleeve for maintenance. A mechanical seal serves as the primary sealing mechanism, utilizing a ceramic seat with EPT rubber elements. This assembly operates at a maximum pressure of 125 PSI without a wear ring and includes suction and discharge pressure tappings along with flush seal line taps to allow for filter installation.
The 3 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and is powered by a 380-460V 3PH electrical supply, resulting in a DOE PEI rating of 0.46. 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.
