Description

The AEUH 20HP 2-Pole Cast Iron Flange Mounted IE3 Premium Efficiency Motor features B5 flange vertical mounting. Rated speed 3530RPM with 91.7% efficiency at IE3 Premium Efficiency class, frame 160M, designed for vertical high-flow feed pumps, industrial process main pumps and similar vertical equipment. The B5 flange face bolts directly onto the pump or driven equipment for a compact vertically-suspended integration, ideal for pump towers and vertical skids. VFD-compatible design with low THD allows precise flow control of vertical pumps via variable-frequency drives. Cast iron housing and brackets deliver excellent structural rigidity, with stable axial load distribution during vertical operation and lower vibration and noise than comparable aluminum-frame vertical motors. The die-cast aluminum rotor integrates fan blades, bars, and end rings in a single casting for superior starting performance. The TEFC totally-enclosed design achieves IP54 protection for long-term stable operation in dusty and humid environments. Universal voltage 200V to 480V at 50/60Hz allows a single SKU to serve power grids worldwide. Fully certified to UL (North America), BSMI (Taiwan), and CE (Europe); IEC frame 160M flange dimensions meet international standards for direct interchangeability with market vertical equipment.
