Double Diaphragm Paint (Sprayers) Pumps

Double diaphragm pumps are a simple and proven means of spraying or transferring adhesives, coating, and stains. Common spray technologies are: compliant (HTE), conventional, and HVLP. Anything you can spray through a pressure pot you can spray with a diaphragm paint pump.

Compressed shop air operates these pumps at a 1:1 ratio of incoming air to fluid pressure. Either an accumulator or a fluid regulator, or both are used on the outlet side of the pump to smooth out the minor pulsation from a double diaphragm pump as it alternates from side to side. Unlike the basic diaphragm pump from an industrial supply house, which are capable of transferring products that have the viscosity of water. Diaphragm paint pumps are configured for the coating industry and are more robust, and have materials compatiable with all adhesives, coatings, and stains.
