This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The pump integrates a dry shaft design to prevent circulating fluid from contacting the stainless steel shaft, which is covered with a replaceable bronze shaft sleeve. Sealing is accomplished by a ceramic mechanical seal with EPT rubber elements. The assembly operates at a maximum pressure of 125 PSI.
The 20 HP Premium Efficiency TEFC motor operates at 3450 RPM and utilizes Aegis Grounding with a 380-460V / 3PH power supply, resulting in a DOE PEI of 0.47. 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.
