Submersible Pumps
DESMI’s submersible pumps are engineered for efficient, continuous operation in demanding environments such as aquaculture facilities, marine systems and industrial water processes.
Built on decades of experience in fluid handling technology, our submersible water pump range combines robust design with hydraulic efficiency, delivering reliable performance where durability and low energy consumption are critical. Whether installed in tanks, wells or recirculating aquaculture systems, DESMI’s solutions are designed to maintain stable flow and ensure dependable service over a long lifecycle.
Applications in aquaculture and recirculating systems
In modern aquaculture, stable circulation and oxygenation are vital for ensuring healthy aquatic environments. DESMI submersible pumps are widely deployed in fish farms, hatcheries and recirculating aquaculture systems (RAS), where reliability and water quality are paramount. For larger fish farming applications, DESMI also provides specialised high-flow, low-pressure pumps for aquaculture systems designed for sustainable facility operations.
- Water circulation and oxygenation: Maintain uniform water conditions across tanks and ponds.
- Water intake and discharge: Handle freshwater and seawater in hatcheries and RAS facilities.
- Temperature and filtration control: Support heat exchange, filtration and sediment management.
- Compatibility: Suitable for both freshwater and seawater applications, resistant to debris and biological materials.
Through continuous operation, these pumps contribute to optimal fish welfare, efficient feed utilisation and stable production conditions.

FAQ - Understanding submersible pumps and aquaculture applications
What is a submersible pump?
A submersible pump is a sealed pumping unit designed to operate entirely underwater, drawing and discharging liquids from below the surface.
How does a submersible pump work?
The pump’s motor drives an impeller that generates hydraulic pressure, moving liquid through the casing and discharge piping while the motor remains sealed against water ingress.
Why are submersible pumps important in aquaculture?
They maintain stable flow and water quality, providing circulation and oxygenation that support fish health and efficient system operation in hatcheries and RAS facilities.
How long do submersible well pumps last?
Service life varies by application and maintenance but, with proper care and full submersion during operation, DESMI pumps can deliver reliable performance over many years of continuous use.
How do I maintain submersible pumps?
Regularly clean the intake and impeller, inspect seals and cables, ensure the pump remains submerged, and follow the manufacturer’s servicing guidelines.
What are the best submersible pumps for fish farms?
Pumps with corrosion-resistant materials, efficient hydraulics and compact construction - such as DESMI’s submersible pump range - are most suitable for modern aquaculture systems.
