This base-mounted end suction pump integrates a cast iron casing with a bronze impeller and a bronze shaft sleeve mounted on a stainless steel shaft. The assembly utilizes a dry shaft design rated for 125 PSI operation that precludes fluid contact with the shaft, while the mechanical seal comprises a ceramic seat and EPT components. Pressure tappings appear on both suction and discharge connections for monitoring system performance. The hydraulic design provides steady flow control while the construction supports field maintenance without disruption to the system piping.
The 20 HP premium efficiency TEFC motor operates at 1750 RPM, integrates Aegis grounding, and accepts 380-460V / 3PH power input, achieving a DOE PEI rating 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
