NMB coupling stays cool

EagleBurgmann, Nova Magnetics, magnetic couplings, MagnetkupplungenAt the synthetic fiber manufacturing facility at Teijin Aramid, the Netherlands, a heat transfer pump is sealed with a high-efficiency NMB-22P-6R-65-00 magnetic coupling. The heat transfer oil can reach temperatures of up to 315 °C (599 °F). The patented low eddy current gap trap keeps the power losses – and heat generation – down despite the high drive power of 45 kW.
