Padus PRO
Submersible pump
The portable submersible pump for reliable and long-term drainage of excavations.
- High reliability in abrasive fluids thanks to rubber-coated hydraulics and an impeller made of Duplex chrome steel
- Easy installation thanks to low weight and flexible discharge connection (vertical/horizontal)
- Active cooling for reliable continuous operation
- Continuous duty in slurping operation thanks to passive cooling
- Easy maintenance thanks to quick access to wearing parts
- Equipped with energy-efficient IE3 motor technology as standard
- Highest operational reliability thanks to integrated protection function

Construction
Submersible drainage pump as submersible close-coupled unit for portable wet installation.
Hydraulics
The discharge-side outlet is designed as a vertical threaded connection with a Storz coupling. If necessary, the outlet on the pressure side can be aligned horizontally. Semi-open, multi-channel impellers are used in the process. The inlet has been equipped with a suction strainer. Consequently, coarse elements in the fluid are filtered upstream of the suction port.
Motor
IE3 motors are available in single-phase and three-phase versions. Motors feature thermal motor monitoring. The motor is cooled by the sheath flow cooling. Continuous duty is possible when immersed/non-immersed, also in slurping operation. A sealing chamber protects the motor from fluid ingress.
The connection cable is permanently connected and the cable is 23 m long:
- O-version: Cable with bare ends
- A-version: Cable with float switch and plug
- P-version: Cable with plug
Seal
The sealing on the fluid side and on the motor side is performed by two bidirectional mechanical seals.
