Melbu Systems started eight years ago the development of a new type of fish pump.
It was the same year, built a prototype, which was used for testing and improvement of the pumping system.
To achieve a funksjonabelt pump system had to be tested several solutions, which then led to todays patented CWC fish pump.
CWC stands for continuous water circulation, and this is pumped strength compared to a conventional vacuum pump.
So how does a CWC pump? A CWC fish pump filled with water at the start of pumping. Pump, suction hose and pipes are kept filled with water all the time.
A sea water pump to pump the water out of the pump tank, so that sucked water and fish into the other end of the pump tank.
When the tank is full of fish, sea water pump starts to pump water into the pump tank, so that the fish flushed out of the tank and the end of utløpsrør (pronounce ment Fund).
Can a CWC pump be the solution to your problems? A CWC pump handles large volumes of water.
It also removes quickly large amounts of air, for example. when the system is to be filled with water or suction funnel to be moved.
This is ideal when pumping cod or saithe not in the sea.
It is also ideal when pumping of farmed fish from Mære, you do not need the fish too much together, only so much that it caught the water sucked in sugetrakta.
New, oxygen rich water is supplied at all times, so that transport over long rørstrekninger not a problem.
Greater lifting height, possible to lift 30-60 feet. Lifting height is determined by the seawater pump.
Full control of water velocity. Eg. then give half the speed of seawater pump half of the water velocity.
This is important when one wants so gentle pumping as possible on slow-swimming fish such as cod, but also require higher water rate of pumping of salmon and trout.
Common problems when using a traditional, simple vacuum pump Anyone who has pumped the fish with a simple vacuum pump with a pump tank, know how difficult it is to get enough fish.
The problem is simply that the vacuum pump must stop when the tank is filled up with water. When you start pumping, as it sucked up some water before you get pulled fish into the suction hose. If it then goes for a long time before you start to get into fish, so it will get much water into the tank, then filled quickly without giving up enough fish.
This causes the fish to be needed together as much as possible, which is very unfavorable in terms of stress and damage to the fish.
This also leads to another problem, which is that the fish comes into the tank while
