Padus UNI
Submersible pump
The flexible drainage pump for a diverse range of fluids.
- Exceptional reliability owing to corrosion-free hydraulics for universal applications and various fluids
- Low weight, integrated capacitor at the AC motor and threaded connection allows for easy installation
- Quick maintenance facilitated by direct access to the sealing chamber and pump housing
- Long maintenance intervals resulting from a double mechanical seal and large volume sealing chamber
- Clog-proof thanks to the integrated strainer



Design
Submersible pump for stationary and portable wet installation in intermittent operation.Liquid
