Diaphragm pump paint sprayers, ideal for wood wall house latex enamel lacquer painting

Airless sprayers – diaphragm pump

The Diaphragm pump airless sprayers could generate very stable spraying pressure

A diaphragm pump airless sprayer also uses a piston, but the piston moves hydraulic oil to move the diaphragm, which in turn sucks up the paint and then pushes it through the hose and gun.

No moving parts touch the diaphragm. The movement of the piston and hydraulic fluid cause the diaphragm to move up and down very rapidly.

There are no packings in the Diaphragm Pump Airless Sprayers, but check valves are still necessary. Specially you need to check the Suction valve, out valve, pressure regulating valve, prime valve. and the diaphragm need to be replaced before its lifetime
