This close-coupled end suction pump comprises a cast iron casing and a bronze impeller for fluid movement. The construction integrates a bronze shaft sleeve and a dry shaft design rated for 125 PSI with a wear ring. A mechanical seal utilizes a ceramic seat half and EPT rubber. Flush seal line taps are provided, allowing for the installation of a filter to protect the seal from non-condensable particles. Pressure tappings are integrated into the suction and discharge connections to facilitate system monitoring.
The assembly incorporates a 20 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis grounding on a 380-460V / 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 an electro-mechanical bypass with main disconnect and 5kA SCCR drive fusing, and holds an enclosure NEMA Type 3R / IP 64 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
