What is an airless spray pump?
An airless spray pump propels materials, at a surface using pressure from a hydraulic or pneumatic pump.
Airless sprayers work by drawing material, such as paint, into a pump under suction. This is compressed using hydraulics or pneumatics at high pressure. The material to be applied is then pushed through the top of the spray nozzle, through the tip, where it is atomised.
Atomisation refers to the process of breaking up fluids into small droplets. An everyday example of this is placing your thumb over the end of the garden hose, as you can see below on the right-hand side of the child. If you do this, you break the stream of water, forcing it into tiny droplets, and creating a mist.
The purpose of atomising is to increase the reach of materials, to allow them to cover a wider area. This helps it to go further and speeds up application time.
