Device for seed treatment with Archimedean screw with flexible based trough for a treatment liquid receptor tank (2) with an agitation device and an electric emptying pump. The delivery pipe of the pump has a bypass situated at the top of the tank which takes part of the output liquid for seed treatment and returns it to the bottom of the tank to keep it permanently agitated. The output of the pump goes to a peristaltic pump driven from the screw and through chargeable rubber wheels. In the pump a band of silicone foam is stuck to the inside of the pump under the nitryl silicone tubing to softly punch the tubing and impair the sealing.
