This close-coupled end suction pump utilizes a cast iron casing, a bronze impeller, and a bronze shaft sleeve to facilitate fluid movement. Its dry shaft design protects the internal components by preventing contact with the circulating fluid, accommodating pressure ratings up to 125 PSI without the use of a wear ring. The assembly incorporates a mechanical seal constructed with a ceramic seat half and EPT rubber. Integral flush seal line taps allow for the installation of a filter to shield the seal from non-condensable particles. The construction integrates suction and discharge pressure tappings for system monitoring.
This 20 HP premium efficiency TEFC motor operates at 3450 RPM and incorporates Aegis grounding for protection, utilizing a 380-460V / 3PH power supply with a DOE PEI rating of 0.44. 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.
