This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller. It utilizes a bronze shaft sleeve and a mechanical dry shaft seal assembly composed of ceramic seat material and EPT rubber. The design supports a pressure capacity of 125 PSI without the use of a wear ring. The assembly facilitates seal maintenance through a slip-on shaft sleeve, while flush seal line taps accommodate the installation of an external filter. Suction and discharge connections include standard pressure tappings for system monitoring.
The 3 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and accepts 380-460V / 3PH power supply, resulting in a DOE PEI of 0.43. 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.
