CP 3 Classic Knapsack


Robust and durable thanks to its unique diaphragm pump system combined with the pressure control valve: the ideal knapsack for your crop protection.

The diaphragm pump system of the CP Classic creates the pressure through the deformation of a highly flexible diaphragm, the limited friction action of this diaphragm avoids premature wear to the pump due to dirty water.

The pressure can be set at low (L) position pressure setting for the spraying of herbicides and at high (H) position for insecticides and fungicide applications.
