The pump casing is an important part of the pump body. After casting, rough machining, and fine machining, the pump casing often needs to be sprayed with a layer of paint on its outer surface to enhance the anti-corrosion and anti-rust capabilities of the pump casing.

[0003] Through searching the prior art, it was found that the Chinese patent with the announcement number CN210753361U discloses a water pump casing spraying device. After the water pump is started, the paint in the paint box is drawn into the liquid outlet pipe to spray the rotating pump casing.
