![]() If you just rinsed it out and put it in the garage you will have some work to do. Graco Pump Armor, and stored it nicely, spring cleaning should be a breeze. If you thoroughly cleaned it, used a pump preserver, such as ![]() Like people, airless paint sprayers come in many shapes and sizes.This will vary depending on how well your paint sprayer was put away at the end of last season. The seals in the fluid section which make the pump work. The filter inside the handle of the gun - the 2nd line of defense against remaining debris in the paint. The filter within the sprayer which is the first line of defense against large particles in the paint. The tube that returns paint to the bucket during priming of the pump. The tube that paint or other material to be sprayed is drawn into. The switch valve that sets the airless sprayer mode to either Prime Mode or Spray Mode. Some other airless parts that are within or in addition to main components you should be familiar with: Prime / Spray Valve There are a few other airless sprayer design types such as Convertibles and Roof-Rigs - these 2 are hydraulic sprayers. We need something to hold all these components together! There are three common chassis design configurations Stand (also called a "skid"), Hi-Boy (sometimes called an "upright cart") and Lo-Boy (sometimes called an "low-profile cart"). There are 2 main types of pressure controls Electronic and Mechanical. Since we can't control pressure with the gun, hose or tip, we need a pressure control. Graco tips can be turned 180° to easily blowout clogs.Orifice shape determines the spray pattern size - height and width.Controls the amount of fluid being sprayed by using different orifice (opening) sizes.Because of this, it is a good idea to have several different tip sizes in your painting kit. The spray tip controls both the spray-fan size and the amount of fluid that is allowed to come out. We also need to be able to easily and safely turn on and off the flow at will. Gunįor an airless to work the system needs to stay pressurized so we need to hold back the fluid until we need it. This is no regular piece of hose!

Next we need to get the pressurized liquid out of the sprayer and to the gun & spray tip. Also something to think about when purchasing a new sprayer. Graco's Contractor Series paint sprayers come with a lifetime drive train warranty. Like a transmission, and axels in a car, the drive train in an airless gets the power to where it needs to go. The motor would be useless if it is not connected to the pump. Definitely something to consider when purchasing a new airless. Graco's Contractor Series electric paint sprayers come with a lifetime motor warranty. Most airless paint sprayers use electric motors followed by gas engine driven sprayers. Probably the second most important component is the motor, the power that pumps the pump. Current Graco Endurance Pumps also come equipped with V-Max packings for longer life. Some fluid sections such as Graco's Endurance Pumps have additional features like their Chromex Rod for longer wear. ![]() Airless pumps are normally made of hardened, heavy-duty steel so they can create the high pressure needed to atomize paints and other "sprayable" materials. It is what moves and pressurizes the material to be sprayed such as latex paint. The heart of an airless paint sprayer is the pump, also called the fluid section.
