This close-coupled end suction pump utilizes a cast iron casing and a bronze impeller. The assembly incorporates a bronze shaft sleeve and a dry shaft mechanical seal design with ceramic seat halves and EPT rubber components, sustaining pressures up to 125 PSI. This design allows for the installation of filter-equipped flush seal lines to protect the seal from particles within open systems. Pressure tappings on the suction and discharge connections provide access for monitoring system conditions.
The 20 HP premium efficiency TEFC motor operates at 3450 RPM and integrates Aegis grounding with a 200-230V / 3PH power supply, resulting in 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.
