The fish vacuum pump is especially suitable for fish harvesting or for the lifting of fishes to grading machines or the loading of transport tanks etc. Compared with impeller pumps, the vacuum pump can suck and sort and transfer fish without hurting. The functional principle is relative easy but effective, which helps to reduce unnecessary breaks and expensive repairs. The fishes (up to 5 kg in body weight and up to 16 t/h) are sucked up to 2 m in height, via an inlet funnel over a suction hose by two vacuum tanks which work in exchange. By a 0.6 m2 large separator with 8 mm grid distance, the fishes are separated from water and glide so, in the optionally connectable scale or directly into the grading machine etc.
