How does a backpack sprayer work?

To get you the best possible results, we first had to understand how a manual backpack pressure worked and we think it is a good starting place for you as well. Not only is it a nice idea to be a genius by understanding how your equipment works but it will also help you make the right pick when facing the quagmire of features that some of these equipment has.

So, let’s get started. A standard backpack sprayer comprises of a liquid-holding tank where the product mix is, a pump and a pump lever, a pressure-holding chamber, a hose and wand and a control valve. That sounds like a lot of confusing parts for something that will only work in your garden but in a minute, it will all make sense.

The first part of operating the pump is by pumping the lever up and down. This piles up pressure in the pressure holding chamber and at the same time draws the liquid from the liquid holding tank. Once you press the valve on the wand, the liquid comes out under the pressure. The functioning is as simple and as straightforward at that.

Best Backpack Sprayer Buyer’s Guide

A good backpack sprayer will save you time and effort and will make your mission of keeping your garden relevant and productive easier and more fun. To make the dream of having a weed free garden a reality, here are some tips to help you make the right choice on the hardware that is going to help you achieve that.

  • Type of sprayer – If there is one thing you should not get wrong, it is the type of the backpack sprayer. Luckily, there are only three main types so choosing one should not be much of a problem. The diaphragm backpack is built to withstand the corrosive nature of chemicals. They happen to last longer and they are easier to repair.

Compared to diaphragm sprayers, piston sprayers are able to generate more pressure. Piston sprayers are great for working in large areas and tall plants like tall shrubs and trees. They are typically less expensive but, they cannot be used with as many chemicals and most herbicides.

The last type is the battery operated sprayers. You don’t have to worry about the technicalities. In this case, battery operated sprayers just save you the trouble of constantly pumping.

  • Weight – considering that the sprayer is going to be on your back for as long as you are using it, weight is going to be an issue. Ideally, they are built to be portable but not all of them are going to be lightweight. When making the choice, you might want to consider the weight of the sprayer.
  • Shoulder strap – even though shoulder straps will not help in the efficiency of the sprayer, it is going to go a long way in helping you enjoy your evening without having to worry about aching shoulders. If you can get a sprayer that has other harnesses and lumbar support even better.
  • Capacity or size – Choosing the capacity of the sprayer is going to be tricky. While having a larger sprayer will save you from having to fill it frequently, it is going to be really heavy. It is up to you to pick a size you feel balances both options for you and offers a common ground.
  • Filters – once you have selected a good and capable backpack sprayer, you want to keep it functional for as long as possible. Having filters will help with this. In this case, the more merrier.

Spraying it down

As you might have realized, getting a good backpack sprayer is not as straight forward as having something that simply pushes out a jet of herbicides.
