With the popularization of electrophoretic paint, electrophoretic coating lines have been erected one after another.

The main circulation system is mainly composed of pumps, valves, filters, pipes, nozzles,

There are strict requirements on the selection of the size and quantity of the circulating pump

Types of circulating pumps

In the electrophoresis tank liquid circulation system, horizontal or vertical centrifugal pumps are generally used

Why not use a high speed circulating pump?

① High rotation speed will cause the local temperature of the tank liquid in the pump to be too high.

② The high shear force of the rotating speed increases, and the high shear force easily causes the emulsion particles of the paint to be demulsified, and the inorganic pigment and filler components are peeled off and precipitated from the organic resin components.
