This close-coupled end suction pump utilizes a cast iron casing with an internal bronze impeller and a bronze shaft sleeve. The assembly integrates a dry shaft design that prevents fluid contact, accommodating a mechanical seal with a ceramic seat half and EPT rubber components. Rated for 125 PSI operation without a wear ring, the pump incorporates flush seal line taps for filter installation and includes pressure tappings on both the suction and discharge connections to monitor system performance.
Power is provided by a 20 HP premium efficiency TEFC motor operating at 3450 RPM, which integrates Aegis grounding and a 380-460V / 3PH power supply, resulting in a DOE PEI 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
