This end suction pump is constructed with a cast iron casing, a bronze impeller, and a bronze shaft sleeve installed over a stainless steel shaft. The dry shaft design prevents contact between the circulating fluid and the shaft, supporting a 125 PSI operational rating without a wear ring. A mechanical seal consisting of ceramic and EPT components seals the assembly.
This assembly utilizes a 3 HP premium efficiency TEFC motor that operates at 3450 RPM and incorporates Aegis grounding, powered by a 380-460V 3PH supply with a DOE PEI rating of 0.49. 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.
