This end suction pump utilizes a cast iron casing with a bronze impeller and a bronze shaft sleeve mounted on a stainless steel shaft. The dry shaft design prevents circulating fluid from contacting the shaft. Mechanical seal components consist of a silicon-carbide seat and EPT rubber. This assembly operates at a maximum pressure of 125 PSI without a wear ring.
The 3 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and accepts 380-460V 3PH power with a DOE PEI rating of 0.47. 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.
