In a nutshell, Graco Airless Texture Sprayers are designed to use heavy, high viscosity products. Common Airless Paint Sprayers do fantastic with medium to low viscosity materials, but are not as excellent with the greater viscosity products, where every PSI counts. An Airless Texture Sprayer can do both! This is because almost every part that touches the liquid being sprayed is large when compared to a specification-equivalent Airless Paint Sprayer. From the pump, all the way to the gun, parts are created with big openings developed to reduce backpressure and make the most of flow. This would be similar to putting a big size exhaust system on your automobile to take full advantage of horsepower.
When comparing Paint and Texture sprayers, the first thing that aesthetically sticks out is the place of the pump foot-valve (figure a). The pump foot valve is the opening at the bottom of the pump where the material enters, and where the check ball system is situated. There are generally two different styles of airless pumps, paint pumps and texture pumps. On a paint pump, this foot valve rises from the ground and makes use of a siphon tube. Think of the siphon as a straw, from which the pump uses to suck the material from a pail. On the other hand, a texture pump has a longer pump body, no siphon tube, and the foot valve lies near the ground. This eliminates the need to draw through a "straw". This ends up being very essential when attempting to suck heavy materials into the pump. Believe how difficult it is to draw a thick milk shake through a straw, and you start to get the idea of what a paint pump would be confronted with. A texture pump would be comparable to putting your face right into the milk shake: no straw needed. Bad table good manners, but certainly reliable! Aside from the noticeable pump distinctions, there are also internal pump differences, while not apparent, play an important function in excellent pump performance with high viscosity materials. The majority of these distinctions are in the foot valve design. Without getting too technical, let's simply say that these components have actually been fastidiously optimized to most effectively pump low and high viscosity products. At, we call this Technology.
MaxFlo is an innovation unique to Graco, and it is standard on all of our Airless Texture Sprayers. To put MaxFlo into real-world perspective, when comparing pump inlet circulation data (with high viscosity material) in between a texture pump and a paint pump, MaxFlo provides 4X more material to the pump than a specification-similar paint pump. This is crucial to getting the needed efficiency for heavy-bodied product. If you can't fill the pump, you can't efficiently spray the material, so the game is already over. matter what you are spraying, hose pipe selection is constantly essential. Whether you are talking hose size, pipe length, pressure rating, or other variables, it is important to correct functioning of the spray system to have the properly sized pipe for the job. Usually speaking, bigger is always better! The bigger the hose suggests less backpressure, which in turn indicates more pressure offered at the weapon. Understanding this, texture sprayers come equipped with bigger size hose than an equivalent paint sprayer. This results in 2X the flow location to move material, less pressure drop, and more available pressure at the weapon. Once once again, taking full advantage of flow is key.
Pump and hose pipe design is not the only thing that goes into creating maximized flow. The design of the gun is critical to peak efficiency. Why make the most of flow through all the other elements, only to have it choked down at the weapon? This is why all Graco texture sprayers have special weapons designed and enhanced for maximum circulation. This consists of removing barriers such as filters and oversizing Additional reading passageways to increase circulation and decrease material pack-out. To put it in viewpoint, texture guns have up to 5.5 X bigger internal passageways than paint weapons. This is another method Graco increases flow and minimizes backpressure. Looking at standard paint guns, they normally have extremely small size passageways and make use of filters. This is due to smaller suggestion orifice sizes used with paint, which can block without filtering. While this is a great setup for lower viscosity products, it is not ideal for much heavier bodied materials with high viscosity. Luckily, both paint and texture guns are able to use the same spray ideas. All Graco Airless Texture Sprayers come equipped with RAC X SwitchTips, which are created to have the longest long lasting fan pattern in the market. They also have the widest variety of idea sizes, including WideRAC, which can spray up to a 24 inch spray fan.
