This close-coupled end suction pump is constructed with a cast iron casing and a bronze impeller for fluid transport. The assembly integrates a bronze shaft sleeve within a dry shaft design that permits operation at 125 PSI without a wear ring. A mechanical seal comprising a ceramic seat half and EPT rubber maintains system integrity, while flush seal line taps and standard suction and discharge pressure tappings facilitate external filtration or monitoring.
The 50 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and receives power from a 380-460V / 3PH supply, achieving 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
