优势（Advantages）：
1. Experimentally confirmed hydrodynamic properties of the impeller (blades) improve efficiency and NPSHreq
2. Reduced operating costs due to nominal impeller diameter turned to the operating point
3. Low wear, low vibrations and highly smooth operation due to good suction characteristics and virtually cavitation-free operation over a wide range
4. Multi-chamber housing seal for reliable housing sealing despite varying operating conditions
5. A wide range of standard materials for optimal adaptation to the conveying medium
6. Extended size range for smaller conveying volumes is also possible
7. Easy disassembly due to withdrawal screws at the junction between pump cover and drive bracket
