优势（Advantages）：
1. High operational reliability:
Only static seals are required
Optional anti-leakage device
Shielding can be protected by start-up mounting devices on the outer and inner rotor
Shielding can is self-draining
The pump does not need to be drained when installing/removing the drive unit
2. Versatile:
Silicon carbide plain bearings lubricated by the conveying medium (optionally with DLC coating)
Modular design principle for hydraulic system and magnetic coupling
Various operating modes available
Pump housing and pump cover can be temperature-controlled and heated
3. Low maintenance costs:
Silicon carbide plain bearings lubricated by the conveying medium (wear-free)
Rolling bearings lubricated for life (30,000 hours at operating temperatures below 80 °C) or rolling bearings lubricated with lubricating oil (35,000 hours)
4. Ideal for high medium temperatures:
Thermal insulation allows very low surface temperatures
Cooling fins reduce rolling bearing temperatures
Optional fan impeller extends the temperature range to 400°C
5. ATEX-compliant by special measures Use in a temperature range below the medium temperature
6. High safety through optional series connection of additional secondary and tertiary seals
7. Targeted leakage discharge between barriers possible through optional interfaces
