When AEMCO does Equipment selection it is critical to the success of airless spraying of industrial coatings. Whether you are in the Saudi Market or not, the equipment must be capable of dependably delivering a select coating type at the right application rate, under various operating conditions. Using improper equipment can lead to quality issues, equipment failures, budget overruns, and schedule delays and unhappy customers. Given the stringent quality standards of the oil & gas industry in Saudi Arabia, Graco quality sprayers are equipped to meet these demands.
Providing enough fluid pressure at the gun is the key to airless spraying, as it atomizes the material into a pattern that provides consistent coverage. When selecting airless spraying equipment, users must consider many factors, including the available power source, coating type, application demand, distance between the pump and spray gun, operating environment, portability, and maintenance requirements. AEMCO, a trusted Paint Equipment Supplier analyzes these critical factors and recommends the right Graco Paint Sprayer.
Airless pumps can be powered by air, electric or gas power sources. The selection of power is often determined by the operating conditions and availability of power sources. Aemco’s Key considerations of each source are shown below.

The coating type also plays a key role in spray equipment. Industrial coatings, typically epoxy or polyurethane based, are highly viscous materials (i.e, thick and resistant to flow). Higher pressure pumps allow pumping more viscous materials and optimizing pressures for less viscous materials.
If solvents are used to lower viscosity, one key factor to consider is the length of time the material needs to be sprayable after being hand mixed (hot potted). The proportion of solids in the coating also serves as a key factor. As the solids percentage increases, the amount of solvent decreases, and the pot life decreases.
The application demand, or the rate at which coating needs to be sprayed, is a key factor in selecting spraying equipment. The required pressure to atomize the material determines the appropriate pump. It must also consider tip size for proper coverage, the number of guns, duty cycle, and pump flow rate. At AEMCO, our sales engineers gather this data from applicators to recommend the right Paint Spray equipment on behalf of Graco.
The combination of both pump pressure and flow rate ultimately determines the application rate. While many pumps provide enough pressure to spray coating, they are offered in different sizes.
The flow rate that the pump is capable of achieving also needs to be considered. For example, a sprayer with a larger pump fluid section cycles slower, allowing it to handle more demanding applications efficiently.
To properly atomize and apply coating material, the pump must overcome pressure drop in the hose. As hose lengths increase, pressure drops increase, and additional pumping pressure is needed.
The diameter of the spray hose also affects pressure drop. By increasing hose diameter, pressure drop can be reduced. Elevation of the application area can also affect pressure drop. If the application area is higher than the sprayer, a larger pressure drop will occur through the hose. Coating suppliers and product data sheets can provide additional information on pressure required.
Different operating environments require different spraying equipment. Temperature and humidity often play a key role in selection. As ambient air compresses and exhausts from the pump at a colder temperature, air motors can experience icing issues. A good motor design mitigates icing and possible pressure loss. Some advanced sprayers include thermally isolated poppets on the motors, insulating them from motor castings to virtually eliminate pilot valve freezing.
When using sprayers in hazardous locations, operators must consider the pump type. Regulations generally prohibit gas pumps in these cases. If using an electric pump, agencies must approve it for operation in hazardous locations. AEMCO always recommends ATEX-approved sprayers for hazardous locations.
Portability is another important factor Aemco Sales Engineers considers. when recommending the right Spray equipment. Most sprayers typically come mounted on carts, allowing users to move them around a job site. Pump size also impacts portability. While larger pumps help achieve higher application rates, users should optimize pump size to ensure easy movement. In industrial environments and smaller projects, choosing a smaller, cost-effective sprayer that a single person can maneuver may be the most practical option.
A sprayer that is easy to troubleshoot and maintain not only simplifies operations but also boosts profitability. Consulting with an equipment dealer can advise on ease of maintenance, regular maintenance tasks and anticipated lifespan of wear items for various sprayers.
Some essential maintenance questions to ask:
Each of the factors discussed by Aemco in this article (power source, coating type, application demand, distance between pump and spray gun, operating environment, portability and maintenance requirements) play a key role when recommending an airless sprayer to one of our customers in Saudi Arabia.)
