This base-mounted end suction pump incorporates a cast iron casing with a bronze impeller and a stainless steel shaft. A replaceable bronze shaft sleeve protects the shaft, while the mechanical seal utilizes a ceramic seat half and EPT rubber. This dry shaft design eliminates contact between the circulating fluid and the shaft, maintaining a pressure rating of 125 PSI. Integrally cast mounting feet allow for secure installation, and the volute provides center-line discharge for air venting.
The assembly operates with a 20 HP premium efficiency TEFC motor at 1750 RPM, integrating Aegis grounding on a 380-460V 3PH power supply with a DOE PEI 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
