PG-HydroFlow

Securing the highest level of fish welfare is important to deliver high quality products in the aquaculture industry.

A cooperation between Smir and PG Flow Solutions has resulted in a innovative water-powered live-fish pump.

Hydroflow is a significant contribution to fish welfare – low/no fish mortality – through a non-mechanical fish pumping solution with industry-leading performance.

PG-HydroFlow is a live-fish transfer, non-mechanical pump solution that enables delousing vessels, wellboats and service boats to convey live fish (up to 10-12kg) at a rate up to 350 t/h per pump, without harm or trauma.

Hydroflow is designed and adapted to adjust for the difference in height between fish cage and factory, as well as the tide.

The pump is seawater driven, has continuous flow and no internal moving parts. This ensures careful transport of live fish larger than 6 kg.

Hydroflow is based on the ejector principle. As seawater is injected into the line, it creates a continuous flow that transports the fish to the next ejector point, where the water is recirculated and reinjected into the stream to move the fish further.

• Highest level of fish welfare – no harm or trauma

• No internal moving parts that can harm the fish

• Low-maintenance

• Tried and tested technology
