What are the components of a sprayer?



As you know, sprayer is one of the main equipment for spreading and spraying the poison in different amounts evenly and evenly, as well as saving the consumption of the poison and thus eliminating plant pests.


All farmers and gardeners need sprayers to be able to protect their plants and trees from insect bites. There are different types of sprayers, which are mentioned below:



In this article from Nika Corp website, we will review the sprayer and its components, so stay tuned for the rest of this article for more information.



What is a sprayer?


It is worth mentioning that sprayer is a device that is used for the purpose of uniform distribution and spraying of toxic and chemical substances in order to take care of plants and trees.


Every year, especially in the summer, one or more types of pesticides or chemicals are used by each gardener or farmer and sprayed by the garden.


Some of you do not know the meaning of non-uniform distribution of poison, so it can be mentioned that non-uniform distribution of poison means that in one part of the garden the poison is sprayed with low concentration and in another part with high concentration.


 What is a sprayer?


Very important tips about spraying:


     Distributing toxic and chemical liquids in concentrations below the plant dose does not completely eliminate the need for pest or weed control.


     Distribution with higher concentrations than the consumed dose can also increase the risk of groundwater and environmental pollution, regardless of the fact that it is additional cost and not cost-effective at all.


     It should be noted that the use of sprayers to spray pesticides and chemicals uniformly is necessary and unavoidable.


Sprayer applications:


There are many types of sprayers that may differ from each other in many cases and you may encounter these differences when buying a sprayer:


     Type of poison

     The amount of poison

     Tank capacity

     Pest type

     Spraying method


It can be acknowledged that different conditions of gardens and farms are very effective in choosing a suitable sprayer. It is important to choose a sprayer that meets the expectations and needs of the consumer in terms of performance.


In general, the applications of the sprayer are as follows:


     Killing insects (pesticides)

     Killing mushrooms

     Weed control

     Spraying liquid fertilizer


A very important point that you should know is that for each of the above applications, special sprayers are designed and produced that are only for that purpose, and you should prepare the desired sprayers according to your needs.


Different spraying methods:


There are several methods that you can use to spray. According to the total volume of liquid sprayed per unit area of the ground, spraying methods are divided as follows:


     High volume or HV

     Low volume or LV

     Very low ULV volume


Sprayer applications


What are the components of a sprayer?


Sprayers consist of the following components:


     Sprayer pump

     Sprayer tank

     Sprayer mixer


Below we describe each of the sprayer components, stay with us.


What is a sprayer pump?


It should be noted that the toxic liquids in the sprayer must be in the form of fine particles before they come out of the sprayer nozzle so that the desired garden or land can be sprayed evenly.


It can be acknowledged that the pump or pump provides the necessary pressure for this purpose. The pumps used in the sprayer include the following two types:


  •     Inflatable pump
  •     Hydraulic pump



What is an air pump?


It should be noted that the pump air pump transfers air to an aeration tank containing the liquid, thereby pressurizing the liquid, which is used to disperse it through the spray nozzle.

What is a hydraulic pump?


The hydraulic pump absorbs a certain volume of liquid and is pressurized through the delivery system.



Drive force required for the pump:


A very important point to know is that pumps differ greatly in the amount of pressure they produce. You may be wondering where the driving force for the pumps comes from.


To answer this question, it can be stated that the driving force required for the pumps will be provided in one of the following 4 ways:


    By manual method, Essen means that the pump will gain the driving force with constant hand pressure.

    Traction (manual intermittent pressure through traction and suction)

    Engine (can be electric or gasoline)

    Tractor (powered by tractor motor)


What is a sprayer tank?


It is worth mentioning that each sprayer has a special tank for carrying toxic liquids and this tank is made of a material in which toxic liquids do not cause corrosion and rust in the tank.


Very important points about the sprayer tank

The following can be mentioned:


    This tank is either built-in or is considered separately.


    The capacity of the tank in different sprayers is fundamentally different from each other and varies from a few liters to more than 200 liters.


    In any case, the tank must be large enough to prevent repeated refills, but not so large that it becomes heavy and difficult for the carrier to carry.


    The sprayer tank is equipped with an inlet (valve) with a funnel and filter to fill the liquid.


    To facilitate filling and cleaning of the sprayer, the inlet of the tank will be large enough.


    The lid of the tank must be completely sealed so that the toxic solution does not leak or drip out of it due to movement and shaking.


    The poison must be mixed with water before pouring into the tank and then poured into the tank using a valve strainer.

What is a sprayer mixer?


It is worth noting that most sprayers have a component called a mixer, which is used to maintain homogeneity and concentration of solution (toxic liquid) in the tank during spraying operations.


Non-agitator sprayers prevent emulsions and soluble suspensions. There are two types of sprayer stirrers, which are mentioned below:


     Mechanical mixer

     Hydraulic mixer


The equipment related to mechanical mixer is as follows:





It should be noted that in both cases, this equipment must be used during the spraying operation and the solution must be constantly stirred. Otherwise the solution may not be sprayed evenly.


It is very important that the hydraulic stirrer consists of a tube with several side holes in the free end. This stirrer is placed in the tank and is fed by the pump at the same time as the spraying operation.


This system is known as the Bypass system. Although the operating mechanism of the hydraulic stirrer is not very precise, but for sprayers with large tanks; they are more suitable.


It is necessary to use a stirrer, especially in toxic solutions made with poison powder, as spraying operations may be difficult due to obstruction of the ducts.


What are the types of sprayers?


There are many different types of sprayers that you can prepare based on the type of application and your needs and do spraying work.


Because sprayers are so different in efficiency and accuracy, you need to get the sprayer exactly what you want to achieve, especially in horticulture and agriculture.


A very important point to know is that sprayers that have adjustable pumps (pumps) have the highest level of satisfaction and acceptance for horticultural and agricultural uses among gardeners and farmers.


Because with their help, the distances covered by the sprayed poison can be adjusted, as well as the large amount of sprayed droplets according to their needs, and the environment can be sprayed.


As mentioned, there are different types and styles of sprayers available to the public, each of which is designed for use in a specific application in a wide range of horticultural and agricultural fields.


You need to keep in mind that there are some important things to consider when buying a sprayer. Among the most important points that should be considered when deciding to buy the right sprayer; the following can be mentioned:


The size of the areas where spraying should be done should be considered:

     The number of times the spraying operation should be performed.


     The type of toxin or toxins that should be sprayed on plants and trees in the area.


     How to transport and use the desired sprayer.


In the first part of the article, we mentioned the types of sprayers, now we will explain and review each of the sprayers:


Manual sprayer:


It should be stated that the manual sprayer works in such a way that we take the sprayer carrying handle with one hand and carry it, and with the other hand we apply pressure to the pump lever. This pressure can be constant or alternating, depending on the sprayer model.


It should be noted that the types of hand sprayers that work with alternating hand pressure (combination of pressure and suction) can be mentioned as follows:


    Trigger sprayer,

    Hand pipe sprayer (horn)

    Handheld greenhouse sprayer



Important points about hand sprayer:


    The capacity of the manual sprayer tank does not exceed a few liters (less than 10 liters).


Hand sprayer is used to spray small surfaces and spaces such as home gardens and small gardens.


What is a backpack sprayer?


It can be mentioned that the back sprayer or backpack is similar to the hand sprayer. With the difference that you no longer need to carry it by hand because you have to carry it on your back like a backpack and do the spraying work.


The advantages of the back sprayer include the following:


    One of the advantages of this sprayer is that less pressure is applied to the user.


    Another advantage of this sprayer is that usually the volume of the tank will have more capacity than the manual type (above 10 liters).


    Depending on the model, the back sprayer pump can be either manual or motorized sprayer.


    The application of back sprayer is just like hand sprayer for spraying home gardens, weeding and small gardens.


What is a trailer sprayer?


This type of sprayer has two wheels at the rear and is easily carried by any vehicle from the front. This type will be used for spraying grass, pastures and sports fields.


The trailer sprayer pump is operated by an electric motor or a gasoline motor.



What is a tractor (three-point) sprayer?


It should be noted that the tractor or three-point sprayer is simply connected to the tractor through a 3-point connection, so one of the names of this sprayer is the three-point sprayer. And the following is used for spraying:


    Golf courses

    Sports grounds


    Large grass surfaces


It is very important that the pump of this sprayer works by connecting to the PTO (power axis) of the tractor or electric motor.


What is a wheelbarrow sprayer?


It can be said that wheelbarrow sprayer is similar to wheelbarrow and that is why it is known by this name in Iran. These sprayers have a volume of 50 to 200 liters and will be used for spraying fruit trees and tall ornamental shrubs and green and flowered spaces.


It should be noted that the driving force of the wheelbarrow sprayer pump is provided by a gasoline engine with a power of 3 to 10 hp. With this power, it is possible to spray poison with a length of more than 15 meters. The spraying rate is about 2 to 4 liters per minute.

What is a power sprayer?


These sprayers are in the form of stretchers and are known as power sprayers. These types of sprayers do not have wheels and instead have two handles around their chassis. So two people have to carry it just like a stretcher at the same time.


This type of sprayer is designed for use in difficult mountainous areas and also has a gasoline engine.
