Onshore aquaculture –sustainable solutions for the future
The shift towards onshore aquaculture is driven by concerns over ocean pollution, over fishing, and a growing awareness of marine ecosystems. Onshore facilities enable the removal of fish breeding waste through wastewater treatment plants, preventing the discharge of pollutants into water bodies. By building farms onshore and pumping seawater, the industry gains better control over water quality, leading to more sustainable fish cultivation.
Onshore aquaculture also allows for precise health management. Controlling diseases becomes more effective, reducing the need for medications and minimizing their environmental impact. Additionally, the ability to separate fish by size using grids enhances efficiency and output, meeting the rising demand for seafood sustainably.
Hidrostal’s support for water management in aquaculture
Hidrostal Pumps play a crucial role in optimizing recirculating aquaculture systems (RAS) efficiency. Specifically designed for efficiency, these pumps facilitate seamless water transfer between tanks during cleaning processes. Beyond this, they contribute significantly to maintaining water quality by circulating and oxygenating water, regulating temperature, and aiding in filtration and treatment processes.
The automation capabilities of Hidrostal pumps not only enhance operational efficiency but also minimize water usage and waste. In the context of aquaculture, these pumps support precise water management by:
- Water Intake from the Sea: Facilitating the transfer of seawater into the onshore aquaculture facility.
- Regular Water Circulation: Preventing stagnation and ensuring a healthy aquatic environment for the fish.
- Cooling/Heating Water: Maintaining optimal water temperature levels for fish cultivation.
- Handling Fish Waste and Offal: Efficiently managing and removing waste generated by the fish.
- Moving Water Between Tanks: Supporting the organized movement of water within the facility for various stages of fish growth.
- Live fish transportation

Unique Screw Centrifugal Impeller for aquaculture environments
When it comes to pumping in aquaculture, Hidrostal stands out, offering unparalleled advantages that enhance the efficiency and reliability of your aquaculture systems.
Hereʼs why Hidrostal is the ideal choice for your aquaculture needs:
Screw Centrifugal Impeller for proven performance in demanding environments
→ Large free ball passages – No blockages in raw, unscreened water, reducing plant downtime and enhancing production efficiency.
→ Minimal flow deflection – Fewer changes in direction minimize pump blockage risks.
→ Delicate handling ability – Maintains the vitality of delicate aquatic organisms during pumping.
→ High hydraulic efficiency – Saves on energy costs and requires less installed power.
→ Capacity to handle high solid contents – Reduces process water and energy consumption, enhancing processing efficiency.
→ Adjustable impeller clearance without dismantling the pump – Ensures longer wear part lifespan and lower energy consumption.
Customize your Hidrostal pump to your needs!
Customizing your Hidrostal pump to meet specific requirements is crucial for optimizing its performance in various applications.
Material options
→ Standard cast iron for neutral pH-values
→ Stainless steel, or duplex for pumping sea water / salt water
Installation options
→ Horizontally on base plates. This is the standard installation for dry installed pumps.
→ Vertically on the Hidrostal flow optimized suction stand. Choose this option, where place of installation is limited. The suction stand takes care that the fluid enters the pump with an optimal velocity profile.
Drive options
→ A standard IEC-Motor using an additional bearing frame to absorb the occurring forces from the impeller. Customers’ needs such as special voltage or motor brand can be considered.
→ An immersible Hidrostal motor in case of wet well installation, outside installation or if flooding, e.g. when cleaning the plant, is possible.
→ To save time during maintenance or in the event of a fault, base plates for Hidrostal pumps are also available as easy-dismounting base plates.
Shaft Seal options
→ Double (tandem) mechanical seal with oil filling (also food degradable) or for water flushing.
→ Mechanical cartridge seals
→ Hydraulic parts of Hidrostal pumps are free from silicone.
