Underwater feeding system for land-based aquaculture
Designed for feeding at the surface and underwater, HyFlow provides more even feed distribution across the tank while reducing feed waste and energy consumption.
91.6%
Lower energy cost per ton
Low Opex through water-based transport, using a fraction of the energy required by conventional air-based feeding systems and reducing energy costs by up to 92% per tonne.
Minimal loss
Feed nutrients stay intact during transport.
Consistent feeding
Predictable cycles, day after day.
Overview
What is HyFlow™
HyFlow™ is a waterborne feeding system that transports feed pellets gently from dosing to fish tanks. It provides accurate dosing, even distribution, minimal pellet damage, and stable, automated operation.
System
How HyFlow™ works
Feed pellets are mixed with water and moved gently through the system to the fish tanks.
- Supports pellet sizes from 2–12 mm
- Enables feeding at multiple depths
- Works with both sinking and floating feed
Configuration
Find the right HyFlow™ setup for your operation
HyFlow™ can be delivered as a standalone feeding system or a complete feed logistics setup. We adapt it to your facility, your fish, and how you feed.
-
Option 1
HyFlow™ Feeding System
- Water-based transport from dosing to fish tanks
- One feeding line per tank
- Even feed distribution across the tank
-
Option 2
HyFlow™ Complete Feed Logistics
- From feed intake to feeding
- Accurate, weight based dosing
- Full control of feed type and pellet size from silo to tank
Technology
Water-based vs. air-based feeding
HyFlow™ uses water to move feed, reducing pellet damage and improving efficiency compared to air-based systems.
-
- More even fish growth
- Less feed wasted
- Lower operating cost
Water-based (HyFlow™)
- Gentle transport
- Low pellet damage
- Lower energy use
-
- Uneven fish growth
- More feed wasted
- Higher operating cost
Air-based systems
- High speed and collisions
- More pellet damage
- More dust and waste
Built for fish welfare
Gentle on pellets. Gentle on fish.
By moving feed with water instead of air, HyFlow™ keeps pellets intact, reducing feed loss and waste. More feed reaches the fish, supporting calmer feeding behaviour while helping lower feeding costs.
Observation made at a trout farm:
Improved dorsal fin health in fish fed with HyFlow compared to fish fed with a conventional feeder.
Why HyFlow™
Designed for efficient, consistent feeding
HyFlow™ improves feeding by combining gentle transport, accurate dosing, and reliable operation.
-
Even feeding and better growth
Gentle transport helps feed reach all fish, supporting more even growth across the tank.
-
Better feed utilization
Accurate dosing reduces waste and helps you get more out of every kilo of feed, while using less energy.
-
Reliable, predictable operation
A fully automated system with few moving parts keeps feeding consistent day after day.
-
Integrated and automated operation
HyFlow can be integrated with existing control systems, providing traceability, automation and full control of the feeding process.
Capabilities
How HyFlow™ improves your operation
Can I upgrade from my existing feeding system?
Yes. HyFlow™ can be added to your current setup or installed as a new system. We adapt it to what you already have, so the change is as effective and cost effective as possible.
Do I need a RAS system to use HyFlow™?
No. HyFlow™ works in different types of aquaculture setups and doesn’t require a full RAS system.
How does HyFlow™ distribute feed in the tank?
Feed is transported in a controlled water flow, so it enters the tank gently and spreads more evenly. It also allows feeding at different depths.
Can HyFlow™ help fish welfare?
By delivering feed gently and evenly, HyFlow™ helps create more stable feeding conditions. This can support better fish health and reduce stress.
How far can HyFlow transport feed?
HyFlow can transport both sinking and floating pellets over long distances. Depending on the facility layout, the system can transport feed up to 1,000 metres from dosing to the fish tanks. This provides greater flexibility in facility design and makes the solution well suited for both new facilities and upgrade projects.
CUSTOMERS SAYS
We have tested HyFlow for over a year and decided to invest in additional feeding systems from Pure Salmon Technology.

HyFLow and Njord
A complete feeding solution
NJORD and HyFlow are designed to work seamlessly together. NJORD monitors and controls the feeding process, while HyFlow ensures accurate feed transport and distribution. Together, they provide one integrated solution that manages the entire feeding process, from planning and control to execution.
Both products can be delivered as standalone solutions or combined into one integrated platform. They can also be retrofitted into existing facilities and adapted to existing infrastructure and systems.
