This close-coupled end suction pump comprises a cast iron casing and a bronze impeller. The design integrates a dry shaft and a bronze shaft sleeve to isolate the rotating element from the circulating fluid, while the mechanical seal utilizes a ceramic seat and EPT rubber. This assembly supports operation at 125 PSI without a wear ring and incorporates flush seal line taps to permit the installation of filtration equipment. Suction and discharge pressure tappings are provided for monitoring system conditions.
The 20 HP premium efficiency ODP motor operates at 3450 RPM with Aegis grounding, utilizes a 380-460V / 3PH power supply, and carries 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
