Picking The Right One For Your Needs

best backpack sprayers

It is really important to pick the right backpack sprayer for you since they have all sorts of variations. It all depends on the work you intend to use it for. For instance, if you are going to treat large areas, it would be better to use a motorized pump. It will help you battle fatigue. However, it is more expensive and also heavier to carry.

There are also two types of pumps – a diaphragm or piston-style. They work better with different chemicals, but we will go into more detail later. If you are going to use herbicides it will be a good idea to check our article about good quality rain gauge picks. It’s a simple tool with which you can see how much water does your plants get.

A highly essential thing to have in mind when choosing is if you are going to use oil-based carriers for woody plant control. You need to have parts (pumps, hoses etc.) that can resist the oils. If not, the oil will break them apart after some time. There are a lot of tips and tricks for selecting, maintaining and calibrating backpack sprayers, which can help you in your work.

Components Of a Backpack Sprayer

If you don’t know how a backpack sprayer works, we are here to make it clear for you! It is a hands-free system that is placed on your back. This allows you to move in your desired area and distribute any chemicals you require. It has five main parts:

●      Shoulder straps/ harness

As the name “backpack sprayer” suggests, this type of sprayers is attached to your back. They allow you to move freely around your garden. They have straps or harness that is placed over your shoulders and across your chest. This helps distribute the weight evenly, and you are free to use your hands to perform different kinds of tasks.

●      Tank

Nowadays the backpack sprayers have become really lightweight, because of their compact tanks. They are made of plastic, that is durable, UV protected and chemical resistant. To be perfect for residential use, the size of the spray tank can fit from 2 to 4 gallons of liquid. Even though it is made to be really light, because of the heavy content, they can be exhausting to wear.

●      Pump

Тhe pump draws the fluids from the tank. It sends them to a pressurizing cell, where the liquid is held under pressure by seals and valves. That is up until you squeeze the pumping lever or valve on the rod. The liquid is then sent out through the nozzle in a high-powered spray.

●      Wand

The wand is an elongated shaft. It allows you to transport the liquid inside the pump and spray it where it is needed. Thanks to its length you can reach places you couldn’t before. For example, above your head or on a plant surrounded with thorns or prickly leaves.

●      Nozzle

This is the most important part of the system of the sprayer because it controls the way you spray (the flow and pattern). Most backpack sprayers include a variety of different nozzles. Each one gives you a different type of spray pattern. For example, a narrow or wide, cone or fan, direct or even an adjustable stream.

This can be really handy when you spray different areas. The nozzles that come with the product can usually be adjusted from a steady jet stream to a fan spray. They also give you some other options for a spray pattern, which we will talk about later. Some spigots are able to deliver from 0.3 to 0.5 gallons of chemicals per minute.

An important note to take is that how long will the nozzle last depends a lot on what it’s made of. It might be cheaper to get a plastic one, but it will weaken overuse and time. However, the expensive ones made out of bronze or brass will last you longer and can save you money in the long term.

●     PSI Pressure

Usually, the products of this type can reach up between 15 and 95 psi of pressure. However, there are some that can produce 150 psi. But keep in mind these are professional-grade sprayers. You wouldn’t normally use them just for occasional use for your backyard.  This level of pressure varies between models. But one of the most important things to remember is to assure that the pressure coming from the tank is consistent and it will steadily spray until you release the trigger.

Yet, when the tank gradually empties the pressure will decrease with it, so keep that in mind. Some backpack sprayers have features such as built-in pressure regulator, that will automatically control the pressure and it will avoid any inconsistency.

Types of Backpack Sprayers

Piston vs Diaphragmbackpack sprayer– as we mentioned earlier, backpack sprayers operate in two kinds of ways. Either by mechanical operations or via a piston and a diaphragm pump.

●     PistonBackpack Sprayers

These pumps can be recognized by the up-and-down motion. They are located in a cell inside the tank itself. Normally, they would produce a pressure of around 90 psi, depending on the product you pick. The pressure is created, when you “pump” the lever. Then the liquid is forced out through the wand, where it comes out in a pattern you’ve picked, depending on the nozzle.

These backpack sprayers are a cheaper option. But it is not recommended to use them for highly abrasive chemicals, because they can destroy the piston.

●      Diaphragm Sprayers

This is a more expensive alternative and they work similarly to a piston pump. But they don’t have the internal cylinder. The pressure is created by the pumping of the handle, which moves the diaphragm. This, in contrast to the piston sprayer, is much more resistant to chemicals. So you can use powders and liquids. This pump also gives you quicker pressure when it is needed, but it can require more maintenance.

Manual or Motorized Backpack Sprayers

●      Manual

This is the most common type of sprayers. Their name comes from the fact that they require you to operate the hand pump. The pressurized liquid goes into the wand only when you pump the handle.

They are really affordable, but because you have to constantly pump. They could give you hand fatigue if they are used over a longer time. However, nowadays most manufacturers have taken care of that and helped your great deal! They started making their sprayers with high-powered pumps that make them easier to use.

This type of sprayers is definitely recommended. If you are going to treat smaller infections or if it’s for a smaller sized area, it is good to have one around. Some sprayers have their handle done. So it can change positions to the left or the right hand, which really helps when you’re working. Another option, if you don’t want to invest too much money or if you need to treat only a really small area, is to get the finest hose end sprayers.

 ●     Motorized Backpack Sprayers

This battery powered backpack sprayer is a must if your target is a larger area. If you have a lawn mower or an all-terrain vehicle you might want to look into best tow behind sprayers. They both get the job done quickly, in a short time. These sprayers relieve the pressure off your hands since you don’t have to constantly pump the handle. However, something that could be a deal breaker for most people is that they cost more. They are heavier and they do require extra maintenance.

What Is Spray-Pattern And Spray Quality?

Backpack Sprayer Reviews

That is an easy question! A spray pattern is referred to the shape of a fluid that comes out of the wand. The pattern determines the degree of evenness. This depends on the nozzle you choose.

The term “spray quality” refers to an internationally standardized droplet size classification. There, the droplet size spectrum composed by a nozzle is conveyed through terms such as “medium”, “coarse”, etc. They are used to describe the possible spray coverage and spray drift.

These qualities are published by most nozzle manufacturers. Even though they are voluntarily measured. The fact that they appear on the label makes them a legal requirement to use. This is due to the Pest Management Regulatory Agency (PMRA), they conduct a risk assessment.

Diaphragm Pump vs. Piston pump

●      Diaphragm Pump

An electric motor powers a plastic diaphragm that generates rapid pressure. But there are other pumps regulated by compressed air. Note that there is a difference between the airless piston pump and the diaphragm pump. Furthermore, to ensure control over the created pressure and for uniformed material flow, you’ve got an inlet and an outlet valve.

To regulate the pressure in the required way, you have another control valve. No other electronic elements are installed, that’s why this design is so simple. Due to this, contrary to electronic piston pumps they have no tool, which can detect the pressure requirement, and so to act as a “permanent rotor”. This is why when switched on, the diaphragm pump runs non-stop.

●      Piston Pump

In comparison to the diaphragm backpack sprayer that we just looked at, a piston pump is much more complex. Just like the other one, they are generally powered by an electric motor (there are some exceptions of air-operated models). Similar to the diaphragm pump design and structure, this one also has a valve that ensures a uniformed material flow. Identically to them they also have a pressure regulating valve, which reaches the needed working pressure.

However, the difference is that the electric piston pumps detect the set operating pressure,  it works as a “stable rotor”. Meanwhile, the other one doesn’t have these tools. The pump works only until it reaches the needed working pressure. After that, the motor switches off. While you are spraying the pressure can drop. Then the piston pump immediately identifies the pressure drop and starts to pump the material and it reaches the wanted pressure range again.

In order to use this pump technology, we need electronic control. It serves the role of constantly measuring the pressure through a pressure sensor. After that, it transmits the gathered data to the “electronic brain” of the sprayer, the circuit board. There the needed command is given to the engine. It starts up when more working pressure is needed. It switches off when this pressure reached.

Other electronic elements, such as the digital displays or even the remote controls. They are installed on electronic piston pumps, in order to monitor and control. Also, there is a difference in the maintenance cost for a diaphragm and a piston pump. Considering this difference it may help you in your choice.

Another secret that we can tell you is that the piston pump can generate a maximum pressure of 6 bar. But the diaphragm pump can go no more than 4 bar. The advantages of higher pressure are that it can produce smaller droplets and has a further reach. This is perfect if you want to use it on trees and larger shrubs. However, it’s not that good if you need it to spray weed killer, because the finer droplets are more likely to drift somewhere in the wind. This means that if you are going to spray down, it will be better to use the diaphragm pump. Because it has lower pressure, it doesn’t drift much and it is really good at weed killing.
