In a nutshell, Graco Airless Texture Sprayers are developed to use heavy, high viscosity products. Typical Airless Paint Sprayers do excellent with medium to low viscosity products, but are not as excellent with the higher viscosity materials, where every PSI counts. An Airless Texture Sprayer can do both! This is because nearly every part that touches the liquid being sprayed is extra-large when compared to a specification-equivalent Airless Paint Sprayer. From the pump, all the method to the weapon, parts are developed with large openings designed to decrease backpressure and optimize circulation. This would resemble putting a large diameter exhaust system on your vehicle to optimize horse power.
When comparing Paint and Texture sprayers, the first thing that visually stands out is the area of the pump foot-valve (figure a). The pump foot valve is the opening at the bottom of the pump where the product goes into, and where the check ball system lies. There are basically 2 various styles of airless pumps, paint pumps and texture pumps. On a paint pump, this foot valve is elevated from the ground and utilizes a siphon tube. Consider the siphon as a straw, from which the pump utilizes 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 is located near the ground. This eliminates the need to draw through a "straw". This ends up being very important when attempting to draw heavy materials into the pump. Think how tough it is to draw a thick milk shake through a straw, and you start to understand 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. Not good table good manners, however certainly effective! Aside from the noticeable pump distinctions, there are also internal pump differences, while not apparent, play a vital role in excellent pump efficiency with high viscosity materials. Most of these distinctions remain in the foot valve design. Without getting too technical, let's just state that these elements have been fastidiously enhanced to most efficiently pump high and low viscosity products. At, we call this Technology.
MaxFlo is a technology unique Drywall texture sprayer to Graco, and it is basic on all of our Airless Texture Sprayers. To put MaxFlo into real-world perspective, when comparing pump inlet circulation information (with high viscosity material) 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 required efficiency for heavy-bodied product. If you can't load the pump, you can't effectively spray the product, so the game is currently over. matter what you are spraying, pipe selection is constantly crucial. Whether you are talking hose pipe diameter, pipe length, pressure score, or other variables, it is critical to correct functioning of the spray system to have the properly sized hose pipe for the job. Usually speaking, bigger is always much better! The bigger the hose indicates less backpressure, which in turn implies more pressure available at the weapon. Knowing this, texture sprayers come geared up with bigger diameter tube than a similar paint sprayer. This results in 2X the circulation area to move material, less pressure drop, and more readily available pressure at the gun. As soon as once again, making the most of circulation is essential.
Pump and hose style is not the only thing that goes into creating maximized circulation. The design of the weapon is vital to peak performance. Why optimize flow through all the other components, just to have it choked down at the gun? This is why all Graco texture sprayers have actually special weapons developed and optimized for optimum flow. This consists of eliminating obstacles such as filters and oversizing passages to increase flow and lower product pack-out. To put it in perspective, texture weapons have up to 5.5 X larger internal passages than paint guns. This is another method Graco increases flow and reduces backpressure. Taking a look at traditional paint weapons, they generally have really little diameter passages and utilize filters. This is because of smaller pointer orifice sizes used with paint, which can obstruct without filtering. While this is a terrific setup for lower viscosity materials, it is not perfect for heavier bodied products with high viscosity. Thankfully, both paint and texture weapons are able to make use of the exact same spray tips. All Graco Airless Texture Sprayers come geared up with RAC X SwitchTips, which are designed to have the longest enduring fan pattern in the market. They also have the best series of pointer sizes, including WideRAC, which can spray approximately a 24 inch spray fan.
