优势（Advantages）：
1. Highly reliable operation, with large motors and thermal overload protection, ensuring operation even under difficult operating conditions
2. Long service life due to corrosion-resistant stainless steel shaft and 1 or 2 mechanical seals, independent of the direction of rotation
3. Large channel cross section for larger impurities (free-moving impeller) and high mechanical resistance of the blades to the wastewater (cutting impeller)
4. Easy installation and removal with automatic, screwless connection for fixed installation, leak-proof due to elastic seals
5. Screws in contact with the medium are made of stainless steel and can be easily removed even after many years of use, making them easy to maintain
