Description

The HOYER Y2E2-180L-4 Electric Motor Pump Set is a heavy-duty, dual motor assembly engineered for continuous industrial applications. Each motor delivers a rated power of 34 kW and operates on 400/690V (Delta/Star) with a frequency range of 50/60 Hz. Designed with tropical windings and Class F insulation, the motors are built to withstand harsh environmental conditions and long-duty cycles (S1). The motors are constructed in accordance with IEC 34-1 standards and include Polyrex EM-2 grease-lubricated bearings for extended service intervals—9600 hours for DE and 9500 hours for NDE—with a 25 g regreasing requirement. The B3 mounting configuration and IP55 enclosure provide flexible installation and robust protection in demanding settings.
