QSpray stocks professional-grade backpack sprayers for pest control operators, landscapers, and anyone who needs to treat more ground than a hand sprayer can cover. Choose from battery-powered and manual pump models from Birchmeier, B&G, FlowZone, Maruyama, and Pulmic, in sizes from 2.5 to 5 gallons. Every order over $199 ships free, and we stock the parts, batteries, and repair kits to keep your backpack running for years.
Battery vs. Manual Backpack Sprayers
Battery (electric) backpack sprayers hold steady pressure with no pumping, so your output stays consistent from the first squeeze to the last and your arm doesn't wear out on long routes. Most of our battery models spray for 2 to 3 hours or more per charge, and a spare battery keeps you going all day.
Manual pump backpack sprayers have no battery to charge or replace, fewer parts to fail, and a lower upfront cost. They're a dependable choice for spot treatments, occasional use, or a backup unit on the truck.

Choosing the Right Backpack Sprayer
Pressure: Higher pressure gives you reach and penetration for tree work, eaves, and dense foliage. The Maruyama MS40LI (145 PSI) and FlowZone Typhoon 3 (115 PSI) are built for that. Lower, steadier pressure gives you less drift and more control for perimeter treatments, landscape beds, and herbicide work, which is where the FlowZone Cyclone 3 and Pulmic Pegasus 15 fit. For tall shrubs and thick canopies, the Birchmeier AS 1200 combo uses moving air to push spray deeper than pressure alone.
Tank size: Water weighs about 8.3 lbs per gallon, so a full 4-gallon tank puts more than 33 lbs of liquid on your back before you count the sprayer itself. A 2.5-gallon backpack is easier to carry for interior work, crack-and-crevice treatments, and tight spaces. A 4-gallon backpack means fewer refills on big exterior jobs.
Run time: If you spray all day, choose a model with a long-running battery and add a spare. Each battery model above has spare batteries and chargers available.
Backpack Sprayer Brands We Carry
FlowZone battery backpacks are workhorses for pest control and landscape crews. The Typhoon 3 sprays from 7 to 115 PSI, reaches over 30 feet, and puts out up to 110 gallons per charge. The Cyclone 3 offers 5 pressure settings from 8 to 60 PSI and up to 3 hours of spraying. Both come with TeeJet-style quick-connect nozzles, and we stock FlowZone parts and batteries.

Birchmeier backpack sprayers are Swiss-made and built for professional daily use. The REC 15 battery backpack uses electronic pressure control, adjustable up to 87 PSI, so the spray pattern stays consistent as the tank empties. Its 18V 4.0Ah battery swaps in seconds. For trees, shrubs, and dense foliage, the AS 1200 + REC 15 combo adds a battery-powered blower that carries spray up to 43 feet, with no gas, oil mixing, or engine noise. Birchmeier also makes manual pump models like the Iris and Flox, and the BCS unit for pre-mixing chemicals before you head out.
Pulmic's Pegasus 15 is a lightweight 4-gallon electric backpack with a diaphragm pump, 3 pressure settings, Viton seals, and 4 to 7 hours of battery life. It's a strong value for herbicide and general-purpose spraying. For bigger jobs without the weight on your back, the Pulmic Pegasus 35 holds 9 gallons on wheels.
B&G's 2.5-gallon electric backpack sprayer pairs B&G's proven valves and wands with battery-powered pressure. B&G orders placed before 2 PM MST ship the same day.
