Another good reason for using our non-metallic containment shells: We have subsequently modified the first of three identical pumps for our customer to reduce both the power consumption and the external flush flow for bearing lubrication and magnet cooling significantly. The pump is a magnet drive centrifugal pump series SLM NVO, equipped with our largest hydraulics (400-400-500).
The metallic containment shell has been replaced by a non-metallic shell made of technical ceramics. Through the use of this new containment shell material, eddy currents are eliminated, reducing power consumption by 20 kW and the external flush flow by almost 90%.
