优势（Advantages）：
1. Experimentally proven hydrodynamic performance of the impeller (blades) improves efficiency and NPSHreq
2. Reduced operating costs due to nominal impeller diameter turned to the operating point
3. The cover is designed as a container cover and is used for fixing
4. Durable deep groove ball bearings lubricated for life
5. Vertical design with small footprint
6. Design D:
Variable immersion depth up to 535 mm
V-rings and/or radial seals prevent the conveying medium from penetrating into the deep groove ball bearings
Cantilever design eliminates the need for additional bearings in the conveying medium
7.Design W:
Variable immersion depth up to 2000 mm
Wear-resistant, medium-lubricated SiC/SiC plain bearings
No negative effects due to temporary immersion of the cover in water, as there are no rolling bearings above the cover
