The gear pump is used for the supply of liquid paints, either solvent or water based, for all Sames automatic sprayers.The gear pump ensures a paint flow that is proportional to its rotation speed. Its use ensures a regular and accurate flow. The pump has to be supplied with a product at 0.5 bar pressure. In the case of a distribution system, the product pressure regulator is to be connected before the pump, whereas a flow meter is always connected after the pump. Upstream pressure facilitates priming but also ensures the flow corresponding to the capacity and speed of the pump.
