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.
