Pumps for well boat application

The growing world population is increasing the demand for fish, which is influencing the rapid development of land-based aquaculture systems and on board aquaculture vessels.

For well boats, our high-flow - low-pressure centrifugal pumps are very suited as they require very little space in the vertical installation.
