Like any form of life, plants are significantly affected by the type of their environment. This dictates investing effort and care into maintaining a healthy surrounding, which can also be incredibly time-consuming. But have no worries, the backpack sprayer is here to help you get it all done easier and faster. In this guide, I’ll be giving you all the details you need to know before buying a backpack sprayer.

Selecting the Best Backpack Sprayer

If you’re looking to save yourself a huge amount of time and hassle, then getting a backpack sprayer should be on top of your to-do list. While being portable and quite simple to use, this tool ensures the delivery of all kinds of products to your plants in a controlled efficient way. From insecticides and herbicides all the way to fertilizers, a backpack sprayer proves to be a must-have item that guarantees the dispense of these chemicals both accurately and sufficiently no matter the size of your property.

Features to Look For

Backpack sprayers include various features that we need to wrap our heads around in order to fully understand what we are searching for.

Backpack Sprayer Design

A backpack sprayer usually has a big polyethylene tank to hold the product and a smaller tank where pressurizing takes place. The air enters the small tank and pushes through leading to the release of contents upon triggering via a pump. How the sprayer mechanism is built is a crucial factor to consider before making a purchase. This is divided mainly into two categories: method of operation and pump type.

Method of Operation

Basically, a backpack sprayer is either manually operated or battery powered.

Manually operated sprayers require you to do the pumping which is a huge downside if you use it frequently or your targeted area is spacious. It will definitely be a hindrance should you decide to widen your property size later on. Moreover, spraying patterns are far from consistent. On the upside, they are more affordable compared to motorized types, require less maintenance and of course, demand no charging.

On the other side, battery powered sprayers are automated, which means you get to save your arms and hands from all the pumping effort while also sparing yourself valuable time. Another important thing is the constant spray output they offer. They are also convenient for both light and hefty workloads if you need to cover large zones. Even though they are more reliable, battery-powered sprayers are heavier, more expensive and will need charging.

Pump Type

Backpack sprayer pumps are majorly split into piston pumps and diaphragm pumps.

Piston pumps produce more pressure which means a stronger and further stream, but their use is limited to non-corrosive substances as harsh chemicals will wear down and damage the piston. Piston pumps work through an up and down motion inside the tank which then pushes those chemicals into the spray wand and out for application.

Diaphragm pumps, on the other hand, provide lower pressure. However, you are able to work with all sorts of products, abrasive or not. They are easier to handle, more durable and allow you to use not only liquids but also wettable powders which isn’t possible with piston pumps. With diaphragm pumps, the movement of the diaphragm itself is what creates the pressure.

Pressure

The backpack sprayer pressure translates into the force with which contents are pushed through the wand and out of the nozzle and how far they reach. Generally, pressure in sprayers ranges from 15 psi up to 95 psi. Some types can even reach a pressure of 150 psi. It’s essential for the pressure to remain constant to ensure a steady flow.

Weight and Capacity

The tank’s capacity directly contributes to the weight of your backpack sprayer. The tank itself, being made of polyethylene, is rather light and tough. It’s the volume of chemicals it holds that actually counts.

Typically tanks sizes go from two to six gallons. Obviously, if you lean towards a tank that is too small, it will be lighter but you will lose time due to repeated refilling. While picking a tank that is too large will burden you with unnecessary weight and will possibly waste some product.

Wand and Nozzle

The wand of the sprayer is where leakage most likely occurs. For this reason, you want to carefully select the wand’s material along with tightly secured seals.

At the end of the wand is the nozzle, which I consider to be the key to a flawless performance. It regulates the flow rate, pattern, and coverage. There are several types which you can choose from according to the task at hand.

How to Make a Pick

When choosing a backpack sprayer, it all comes down to your needs. You want your choice to best-suit the size of your property, type of chemicals you’ll be using and your workload. So it’s only wise to determine all that before aiming at a specific model.

Power Source

While a manually operated sprayer is cheaper, it is time-consuming and exhausting if you use it for more than 15 mins. Consequently, a battery operated sprayer is more reliable, efficient and even if you’re throwing in more money, I think it’s totally worth it.

Backpack Sprayer Pump

There’s really no comparison here as the diaphragm type pump is considerably more popular for all the right reasons. It’s more durable, versatile and all around trouble-free.

Tank Size

As we previously established, you should avoid going too small or too big with the tank’s size. A four-gallon tank grants you the best of both worlds allowing for large loads of chemicals with a reasonable weight to support.

Construction Material

Putting thought into choosing the material of which the wand and nozzle are made of, makes such a huge difference in the long run. Plastic wands and nozzles cost less but live less and will often require replacement. Investing in brass or stainless steel nozzles and wands will save you money as they last a whole lot longer.

Extra Comfort

When you buy a backpack sprayer, it’s absolutely necessary to make sure that the shoulder and waist straps are well padded and can sufficiently support the tank’s weight. Remember you’ll be carrying the sprayer, so your comfort level is just as important as the features you’re looking for.

Stay Safe and Secure

Despite the simplicity of working with a backpack sprayer, mistakes can have dangerous consequences. Avoid this by thoroughly reading the instructions manual to completely grasp the ins and outs of the process.

Always wear protective clothing and gear to keep yourself from coming in contact with any chemicals in case seals get loose and leaking occurs. Don’t risk getting a serious injury.

Having a reliable warranty certificate is your guarantee for a high-quality product and an adequate service, so don’t forget to take that into account.
