Their aren’t any obvious downsides to this model. The Oregon 518769 wins with a balance of weight, cost, spraying pressure, and carrying capacity. If, however, you want the lightest, the most powerful, or the most affordable backpack pump sprayer, then you might want to keep shopping.

The Oregon 518771 5-gallon has nearly the same benefits as our No. 1-ranked Oregon model but with these two key differences: You get an extra gallon of tank capacity, but you have to pay a little more. 

This extra carrying capacity is ideal for long jobs and continuous spraying. We also like this backpack pump sprayer’s ergonomic design, comfortable straps, and great lumbar support. 

Bonus points: The 6-foot hose allows for versatility, and the interchangeable nozzles provide a variety of spray patterns.

3. Flesser 4-gallon backpack sprayer 

Flesser Backpack Sprayer 4 Gal Sprayer for Weed Killer, Knapsack Manual Sprayer No Leak and Heavy Duty Suitable for Agricultural Gardening Use

The Flesser 4-gallon backpack sprayer optimizes both cost and weight. Here’s what we mean: At only 6.6 pounds, this little machine is perfect for anyone who has back problems, and it’s also a very low-priced model. 

Where the Flesser 4-gallon backpack sprayer loses a few points is with power. With a maximum of only 58 pounds of pressure per square inch, you’ll find other models with a much stronger spray. If you have a large garden to cover you might want to look for a backpack pump sprayer with a stronger stream. 

Specifications:

  • Tank Capacity: 4 gallons
  • Maximum Pressure: 58 psi
  • Weight: 6.6 lbs
  • Price Range: Inexpensive

Pros:

✓ Lightweight
✓ Affordable

4. Beaugreen 4-gallon backpack sprayer

Beaugreen Backpack Sprayer Pump Pressure Sprayer Garden Weed Killer Sprayer for Lawn Garden Farm (4 Gallon/ 15L-Blue)

The Beaugreen 4-gallon backpack sprayer also combines affordability with optimal weight. We love the easy-to-carry 6.6 pounds, as this machine would be perfect for you if you don’t want to strain yourself while spraying to get rid of weeds or pests. 

We placed this sprayer in the “inexpensive” category, meaning its price was in the bottom third of all the models in our survey. If cost is an issue, this model may be for you. We also like the ergonomic design and the adjustable sprayer head. 

Any drawbacks? The 4-gallon tank is pretty standard. Also, you’ll sacrifice a little power with these lightweight models. The 58 pounds of pressure per square inch is on the low end for this list.  

Specifications:

  • Tank Capacity: 4 gallons
  • Maximum Pressure: 58 psi
  • Weight: 6.6 lbs.
  • Price Range: Inexpensive

Pros:

✓ Lightweight
✓ Affordable

Cons:

✗ Low power

5. Roundup 190314 backpack sprayer 

Roundup 190314 Backpack Sprayer for Fertilizers, Herbicides, Weed Killers & Insecticides, 4 Gallon

This Roundup backpack pump sprayer makes sense as our No. 5 pick as it is right in the middle of the pack for spraying power, weight, and price. 

Bonus points: We like the removable in-line filter to prevent clogging, and the durability and the heavy-duty design. The adjustable padded straps are comfortable, and the wide mouth-lid makes for easy filling. 

The only place this model loses a few points is in price. 

Specifications:

  • Tank Capacity: 4 gallons
  • Maximum Pressure: 90 psi
  • Weight: 10 lbs.
  • Price Range: Medium

Pros:

✓ Strong pressure
✓ Medium weight

Cons:

This backpack pump sprayer loses points mainly for power. Its 58 pounds of pressure per square inch will get the job done, but you may have to stand a little closer to the plants you want to spray and walk around a little more. 

Specifications:

  • Tank Capacity: 5 gallons
  • Maximum Pressure: 58 psi
  • Weight: 9.3 lbs
  • Price Range: Inexpensive

Bonus points: This Field King backpack pump sprayer also accepts TeeJet brand nozzles in case you like to customize with outside parts. We also like the 190328’s lockable shut-off valve.

The only downside? This professional-grade backpack pump sprayer is a little on the heavy side. Don’t drop it on your foot.

Buyers Guide

Do you need a backpack pump sprayer?

Backpack sprayers are handy for evenly spraying your yard with weed killers and pesticides. If you’re struggling with dandelions, aphids, or other common problems, these useful machines can keep unwanted weeds and critters out of your yard. 

A backpack sprayer gives you several advantages over a handheld sprayer. The average backpack sprayer carries 4 gallons of liquid, much more than your typical handheld. 

A backpack sprayer is also usually more powerful. You can simply fit a larger and more powerful pump engine on a backpack. 

But which backpack sprayer is the right one for you? We’ll cover the different power types so you can decide if a hand-pump is the right model for your landscape. 

3 types of backpack sprayers

Backpack pump sprayers have three power sources: gas, battery, or hand pump. Let’s go over the differences. 

Hand Pump: Pump-operated backpack sprayers build up water pressure the old fashioned way, with a hand-powered pump. These simple machines have some serious benefits. They’re often much lighter and more affordable than their gas- and battery-powered counterparts.

Backpack pump sprayers also are the most environmentally friendly type you can buy. 

The downside of pump sprayers is pretty obvious: You have to put in a little more elbow grease to get rid of those weeds or pests in your yard or garden. 

Gas-engine: Gas-powered backpack pump sprayers are powerful and effective at moving a lot of liquid quickly, but gas-powered models are often heavier and much more expensive. They also require maintenance and regular refuelling to run. 

If you’re concerned about cutting carbon emissions, you’ll want to avoid adding more combustion engines to your carbon footprint. Also, gas engines can be loud and smelly. 

Battery-powered: Battery-powered backpack pump sprayers rely on lithium ion batteries to power their pumps. Battery-powered pump sprayers are powerful and portable, but they tend to be heavier and more expensive than pump models.

On the plus side, battery-powered sprayers usually weigh and cost less than gas-powered models. 

One major drawback of battery-powered sprayers? You’ll have to plug in the charger for hours to keep them charged up, so they’re not ideal for anyone who is a little forgetful. 

While better for the environment than gas, battery-powered sprayers use electricity from your house, and that energy often comes from a coal-burning power plant.

Backpack pump sprayers: key metrics

If you have never bought a backpack pump sprayer before, these statistics might be a little confusing. Here is a quick rundown of what each of them means: 

Tank Capacity: The tank is where you store the liquid you plan on spraying, whether it’s herbicides, pesticides, or fertilizers. The industry standard is about 4 gallons. 

Maximum Pressure: Pressure tells you how powerful a stream of fluid your machine can spray. The standard unit of measurement is pounds per square inch (psi). The more weight pushing down on the liquid, the harder it shoots out the hose. 

Weight: The weight of backpack sprayers will range from just over 5 pounds to close to 14. What this means to you will vary depending on your needs and lifting ability.  

Price Range: The cost of these machines will vary. Backpack pump sprayers typically range in price from about $50 to $150. 

FAQ About Backpack Pump Sprayers

1. What’s the best backpack pump sprayer I can buy?

By our count, the Oregon 518769 4-gallon offers the best combination of our key metrics: price, weight, carrying capacity, and spraying pressure.

3. How far can a backpack pump sprayer spray? 

This will depend on your model and how much you pump it. For a range, these sprayers can generally maintain a stream of at least 10 feet and at most 35. 

Conclusion 

Armed with LawnStarter’s list of the best backpack pump sprayers, you should be able to make a better decision about the right model for your needs.

The best way to choose a backpack pump sprayer is to focus on what’s most important to you:

  • Power: Get a powerful backpack pump sprayer if you need some serious hose strength. Anyone who needs to spray a lot can save themselves some time with a stronger jet stream.
  • Price: Buy a more affordable model if price is your top priority. Decide how much you want to spend ahead of time and limit yourself to sprayers in your budget. 
  • Weight: Consider the weight if you’re looking to make your chores easier. We can’t all lug heavy machines on our back for hours on end.

Once you’ve determined what’s most important to you in a sprayer, you can pick out the best backpack pump sprayer to meet those needs. 

Of course, you might decide that spraying everything yourself just isn’t your jam. In that case, we’d be happy to connect you with a lawn care pro near you.
