Applications

Within Aquaculture industry the pumps are suitable as:

Freshwater
Waiter with additives
Seawater

RAS Applications:

Main Pump
Intake Water Pumps

The pumps are suitable for Aquaculture water applications (seawater, freshwater, brackish, water with
cleaning agents, etc.) and for meeting the Aquaculture industry requirements for:

• Design to run 24 / 7 / 365

• Very long intervals between maintenance

• High efficiency > 80% at high-flow & low-pressure
conditions

• Flexibility – can be installed horizontally or vertically
to adapt to any pipe system

• Slow speed (using 6 or 8 pole motors) – very limited
noise transmitted to fish tanks

• Easy installation and maintenance

DESMI Pumps on Well Boats

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.
