This base-mounted end suction pump incorporates a cast iron casing with integrally cast mounting feet. The hydraulic assembly utilizes a bronze impeller and a bronze shaft sleeve installed over a stainless steel shaft. This configuration employs a dry shaft design that isolates the circulating fluid from the pump shaft to prevent corrosion. The mechanical seal consists of a ceramic seat with EPT rubber, suitable for systems operating at pressures up to 125 PSI. Gauging ports at the suction and discharge connections provide access for pressure monitoring during operation.
This 20 HP premium efficiency TEFC motor operates at 1750 RPM and utilizes Aegis grounding, powered by 380-460V / 3PH electricity, with a DOE PEI of 0.45. 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.
