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
Hydraulics
The outlet on the pressure side is designed as vertical threaded connection with 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
AC and three-phase current version IE3 motors are used in the process. 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 filling fluid used is potentially biodegradable and environmentally safe.
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.
