This base-mounted end suction pump is constructed with a cast iron casing and integrally cast mounting feet. The internal assembly comprises a bronze impeller paired with a stainless steel shaft and a bronze shaft sleeve. Utilizing a dry shaft design, the unit prevents contact between the shaft and the circulating fluid. The mechanical seal incorporates a ceramic seat with EPT rubber, providing a 125 PSI rating without a wear ring.
The assembly operates with a 7.5 HP premium efficiency TEFC motor at 1750 RPM, integrating Aegis grounding for the shaft, powered by 380-460V / 3PH current, with a DOE PEI of 0.44. 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.
