- Circulation of water in sewage treatment plants
- Oxygen enrichment of fish farm rearing waters
- Trimming ships, ferries and tankers
- Draining or flooding of floating docks
- Emptying or flooding of tanks
- clean or slightly dirty water with a solids content of up to 50 mg/l
- fresh water, sea water and brackish water
- Pumped medium temperatures up to 50 °C
Executions
- single-stage centrifugal pumps with open semi-axial impeller
- submersible, rewindable and water-filled motors with protection class IP 68
- also available as a highly efficient permanent magnet synchronous submersible motor
- motor cooling through pumped medium that flows around it
- water-lubricated, radial and axial slide bearings
- motor encapsulation by mechanical seal
- optimal motor filling guaranteed by a volume-compensation system

Oxygen enrichment in oyster farming
The po-upl propeller pumps are used as circulation pumps for oxygen enrichment in a French oyster farm. The pumps can be used horizontally or vertically and are operated with frequency converters.
Drainage in flood protection
In Germany, the propeller pumps are used, among other things, as drainage pumps for flood protection. The pumps with inlet basket are mounted on slide rails and have an automatic clutch system.
Use in recirculating aquaculture systems
In Norway and Canada, the po-upl propeller pumps are used in recirculating aquaculture systems (RAS) for aeration and oxygenation of aquacultures.
