How to Use the Controls of a Power Sprayer Correctly

As the demand for more efficient and more effective power sprayers is increasing, engineers are developing more advanced and comfortable equipment that is more precise and light. Innovative designs and features set leading power sprayers apart from the competition. Air circulation system is a helpful feature because it increases the distribution of mist particles.


The sprayer’s pressure gauge shows the spraying pressure at a specific pressure. The pressure range should be at least double the expected pressure. To double the spray rate, the sprayer’s pressure should be increased by at least four times.

The design of a power sprayer is crucial in the application of pesticides. It should be compact and easy to handle, and it should provide uniform pressure in the spraying process. It should also have a DC power backup. Various types of spray chemicals are used in various stages of farming. The chemical used to treat pests may also be biodegradable. 


Power sprayers have several different functions. Those functions include application, atomization, spraying, and cleaning. The hoses must be able to handle the chemicals and pressures that the sprayer is able to produce at the selected peak pressure. When the spray boom is turned off, the pressure is reduced, reducing the rate of spraying. 

The pump should be positioned below the supply tank. The pressure relief valve should be adjusted to 10 to 15 PSI higher than the desired spraying pressure. If this pressure is too high, the agitation control valve should be opened slowly. The throttling control valve is also used to regulate the pressure of the sprayer’s nozzles. 


A good power sprayer has controls to control its various aspects. The rate controller, for example, will allow the applicator to enter the desired amount of spray, then set the pressure of the spray. This pressure is dependent on the spray volume and travel speed. A higher travel speed means higher pressure. Here are some tips to use the controls of a power sprayer correctly.

Before starting to spray, measure the distance you need to cover. A tape measure can help you to measure the distance accurately. Then, measure the time it takes to spray this distance. It’s important to use the same surface as the spraying area, as varying the distance may lead to inaccurate results.

The pressure regulator is important for the safety of the machine. It prevents excess pressure that could damage the pump or the operator. Different pumps use different regulators. The engine is responsible for converting fuel into mechanical energy. Its solution consists of gas and oil in a thirty-one ratio. Lighter engines are easier to transport from jobsite to jobsite.


When choosing a pump for your power sprayer, there are several factors to consider, such as the type of spray solution you plan to use, the flow rate requirements, and the pressure range. These pumps are ideal for applications involving crop performance chemicals.

In selecting a pump for your power sprayer, you should consider several factors. The GPM rating is a base-line measurement for pump performance. This value is based on a standard of pumping water without any restrictions. Deviations from this standard can affect pump performance. 

Piston pumps: Piston pumps feature a piston mechanism to compress the system fluid. Piston pumps are suited for horizontal or vertical delivery of crop fertilizers, pesticides, and chemicals. Piston pumps feature long service lives and are self-priming. 


If you own an electric power sprayer, there are two types of hoses: the male and female quick-connect hoses. These hoses connect to your power sprayer via male and female threads. Those with male connections have an easier time finding replacements and extensions. The female hoses have a longer life span, which means they can withstand more abuse.

Next, you should choose the right hose diameter. A common pressure washer uses a 5/16-inch diameter hose, while a 3/8-inch hose is more suitable for high-pressure applications. You should also consider how much pressure your pressure washer can handle before buying a hose that is too narrow.

When buying a power sprayer, consider what type of tank you’ll need. A PCO tank is commonly rectangular or square and needs a frame to support it. The lowest-cost type of tank is a PCO tank. Other options for a power sprayer include poly tanks, which are able to withstand a wide variety of chemicals. They feature an isolated pump that is free from cross-chemical contamination.
