Being that the best one of the backpack sprayers is very expensive, we are offering you another solution – similar features, but lower the price.

Our alternative for you is the Chapin 61900 which is actually a manual version of the Chapin 63985.

So, if you want to save your strength and time and do the job easily, then the model with an electric pump is better for you. to do the job.

The positive sides of both the Chapin 61900 and the Cahpin 63985 models are that they offer lumbar support, the deluxe padded straps and the 63985 is designed especially for prolonged usage.

The larger the opening is, the better the tank will be cleaned and filled.

You can test whether a 4-inch opening is good enough for you by trying to clean a jar with a 4-inch wide opening.

If you have difficulties, you should think about the model with the wider opening.

Backpack Sprayers: The Ultimate Buying Guide

No matter how great one product is, it will not be ideal for everybody.

That is why the manufacturers are doing their best to suit the needs of every customer.

They are achieving that by producing a device which will have the best features that are important to them.

We created this article to help you find the backpack sprayer which will address all your requirements and which will be satisfactory in terms of economy, comfort, and ease of use.

If you have not found the answers to all your questions, this section might give you some further information with more details related to backpack sprayers.

Sprayer

Should I invest more money in a motorized pump?

In order to explain who is in need of what kind of pump, we will take a look at an example of a baker and a woman preparing food for her family.

A baker breaks a lot of eggs per day and he/she would have great benefits from an electronic device, unlike a woman who whisks two eggs every other day.

An electric mixer is not necessary to her.

The conclusion is that the investment in a motorized sprayer is worth only if you are planning to use it frequently.

If the volume of your work is not huge, a manual one would do the job quite efficiently.

The volume of work which exceeds an hour of spraying every day requires an electric motor so that it can save you plenty of effort and time.

A motorized pump is more of a luxury than a necessity if you are spraying once or twice a week.

Another difference is that a motorized pump also helps maintain pressure, spray pattern, flow rate, and spray quality, meaning that it is designed for professionals.

People growing plants as a hobby should not waste money on electric devices.

What is meant by spray pattern and quality?

The spray patterns depend on the backpack sprayer’s wand.

In those wands which do not have a nozzle, the solution would flow out in a single stream, while in those with a nozzle, the stream would flow into tiny droplets and create different shapes on the sprayed surface.

The spray patterns that are very popular are flat-fan, even flat-fan, extended flat-fan, full cone, hollow cone, and flood.

In the majority of cases the name of the nozzle is the same as the spray pattern it creates.

The size of the droplet coming out of the nozzle is the spray quality.

The most common sizes are: very fine, fine, medium, coarse, very coarse, and extremely coarse.

Which size of droplets to use in mentioned when you buy the product you spray on your plants.

That way you will be able to change the pressure and nozzle to achieve the required droplet size.

The process of adjusting the spray is called calibration.

What should be psi value for a good sprayer?

You probably know that the pressure range is an important feature when backpack sprayers are in question.

The effects of increasing or decreasing pressure are also very significant.

If the pressure is constant, the spray nozzle volume increases with an increase in nozzle size.

If it happens that the nozzle size remains the same, the spray nozzle volume increases with increase in pressure.

Now, the increasing of the pressure reduces the droplet size which can lead to a drift and the missing of the intended target.

So, you will need to calibrate your sprayer and make these parameters right.

The calibration of your sprayer includes the adjustment of the nozzle size and pressure which will in turn reduce drift and improve accuracy.

So, for most users, a pressure range of 20 to 60 psi is considered enough.

What is the difference between diaphragm pumps and piston pumps?

Those who frequently work with a backpack sprayer know that the tank is not under pressure, but the pump is the one that creates the pressure which is necessary so as to spray the solution in a separate chamber.

The pump types are a piston or a diaphragm one and there are differences between them.

Firstly, a piston pump pushes air into the chamber as a cycle pump pushes air into tires.

On the other hand, a diaphragm pump does not have any moving parts and produces no friction.

That way, the pump durability is better and diaphragm pumps work better than piston pumps.

However, if you are using liquids, the piston pump would work better than diaphragm pumps.

I think I got it, what are my options?

Depending on the amount of work that has to be done and how often it will be done, you can decide which backpack sprayer is good for you.

As this list offers only five models of all the available products on the market, you can also visit some other websites and gather more information from different customers and users.

However, if you are looking for a quality backpack sprayer, the brands that you can take into consideration are D.B. Smith, Jacto, Hudson, SPS, Stihl and  Chapin and Solo.

Conclusion

Having taken a look at all the characteristics that the best backpack weed sprayer offer, we can now easily make a conclusion which one is the most suitable for our needs, as various gardeners have distinct desires and expectations from the sprayer.

The first one on our list which deserves much attention is the Chapin 63985 .

You will have amazing benefits of an electric motor.

If you do not need an electric device, you can go for a budget-friendly product – the Chapin 61900.

However, have in mind that these models do not accommodate TeeJet nozzles.

To get a greater flexibility in spray patterns, you should check the Solo 425 or the Field King Professional.

What these models lack are high-quality back straps and lumbar support.

So, they are less comfortable and designed for short period of usage.

The model which offers the least features is the Stanley 61804, a low cost backpack sprayer.

During the recent decades, backpack sprayers have become a tool present in the majority of households and this has caused the increase in number of producers and models on the market.

What is offered are models for every budget and every type of customers.

We hope that now, as you have gone through these reviews, you are able to choose a product that will fulfill your requirements.
