In a nutshell, Graco Airless Texture Sprayers are designed to apply heavy, high viscosity products. Common Airless Paint Sprayers do great 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 due to the fact that almost every part that touches the liquid being sprayed is oversized when compared to a specification-equivalent Airless Paint Sprayer. From the pump, all the method to the weapon, parts are designed with big openings designed to reduce backpressure and maximize flow. This would be similar to putting a big size exhaust system on your lorry to maximize horsepower.
When comparing Paint and Texture sprayers, the very first thing that aesthetically stands 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 product gets in, and where the check ball system lies. There are essentially 2 various 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. Consider the siphon as a straw, from which the pump uses to draw the product from a pail. In contrast, a texture pump has a longer pump body, no siphon tube, and the foot valve is located near the ground. This gets rid of the requirement to suck through a "straw". This becomes extremely crucial 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 concept of what a paint pump would be confronted with. A texture pump would be equivalent to putting your face right into the milk shake: no straw needed. Not excellent table good manners, but certainly efficient! Aside from the noticeable pump differences, there are also internal pump distinctions, while not apparent, play a crucial function in good pump performance with high viscosity products. Most of these distinctions remain in the foot valve design. Without getting too technical, let's simply say that these elements have actually been painstakingly optimized to most successfully pump high and low viscosity materials. At, we call this Innovation.
MaxFlo is a technology special to Graco, and it is basic on all of our Airless Texture Sprayers. To put MaxFlo into real-world point of view, when comparing pump inlet circulation data (with high viscosity material) in between a texture pump and a paint pump, MaxFlo delivers 4X more material to the pump than a specification-similar paint pump. This is crucial to getting the needed performance for heavy-bodied material. If you can't fill the pump, you can't efficiently spray the material, so the video game is currently over. matter what you are spraying, pipe choice is always essential. Whether you are talking tube diameter, hose pipe length, pressure ranking, or other variables, it is critical to appropriate performance of the spray system to have actually the correctly sized pipe for the task. Generally speaking, bigger is constantly much better! The bigger the hose pipe indicates less backpressure, which in turn suggests more pressure available at the gun. Understanding this, texture sprayers come geared up with bigger diameter hose pipe than an equivalent paint sprayer. This leads to 2X the flow area to move material, less pressure drop, and more readily available pressure at the weapon. Once again, taking full advantage of circulation is key.
Pump and hose design is not the only thing that enters into developing maximized flow. The design of the weapon is important to get more info peak performance. Why make the most of flow through all the other parts, just to have it choked down at the weapon? This is why all Graco texture sprayers have special guns designed and optimized for optimum circulation. This consists of getting rid of obstacles such as filters and oversizing passageways to increase flow and decrease product pack-out. To put it in viewpoint, texture weapons have up to 5.5 X bigger internal passages than paint guns. This is another way Graco increases flow and minimizes backpressure. Taking a look at standard paint weapons, they typically have very small diameter passageways and use filters. This is because of smaller sized pointer orifice sizes used with paint, which can clog without filtering. While this is a great setup for lower viscosity products, it is not perfect for much heavier bodied products with high viscosity. Luckily, both paint and texture weapons have the ability to utilize the same spray tips. All Graco Airless Texture Sprayers come equipped with RAC X SwitchTips, which are developed to have the longest long lasting fan pattern in the market. They likewise have the largest series of idea sizes, consisting of WideRAC, which can spray as much as a 24 inch spray fan.
