This end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft sleeve. It incorporates a dry shaft design, which prevents fluid contact with the pump shaft to minimize corrosion risks. The assembly uses a mechanical seal with a ceramic seat half and EPT rubber components. Rated for 125 PSI operation without a wear ring, the design integrates flush seal line taps to allow for filter attachment. Pressure tappings are positioned on both the suction and discharge connections to monitor hydraulic performance.
Powered by a 50 HP premium efficiency TEFC motor operating at 1750 RPM, the assembly utilizes Aegis grounding and functions on a 380-460V three-phase power supply with 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, main disconnect, and drive fusing, and it holds an enclosure NEMA 3R / IP 64 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
