Jacto Backpack Sprayers

Farm, commercial and home! Jacto has the backpack sprayer to meet your needs.

Jacto offers nine models of heavy duty manual Backpack sprayers, also commonly called Knapsack sprayers. Two three gallon, six four gallon and one five gallon model, with similar but distinct features, as well as different color schemes, Jacto gives the user several choices for their different applications.

All nine models come with a fully-internal piston pump contained within the sprayer tank. This design feature eliminates the possibility of the pump leaking on the operator, plus Jacto uses a unique pump rod that attaches to the pump lever at the top of the pump piston. By using a separate pump rod, the piston remains staraight in the pump chamber, reducing the amount of effort needed to pressurize the sprayer and wear on the piston cup. This feature makes makes pumping the sprayer almost effortless and usually on takes 6-8 strokes to achieve 45 psi. The unique design of the Jacto piston pump allows the operator to easily perform field maintenance when needed.

Standard on all Jacto Backpack sprayers are fully adjustable, deluxe, wide, heavily padded straps with a quick cinch/release mechanism, integrally molded top carry handle and pump lever locking feature with wand storage for easy transport and storage. UV resistant and ergonomically designed tanks, that comfortably fit the users back, with large tank fill opening and filter screen. Each sprayer comes with an ergonomic and easy to use trigger valve, stainless steel wand, nozzle screen and adjustable nozzle.
