backpack sprayer has a 4 gallon liquid capacity. The tank of the sprayer is made of high density polyethylene that makes the tank more resistant to breakage and corrosion. The polyethylene tank is treated with ultraviolet inhibitors and provides years of protection from sun damage. The wide-mouth opening of Solo ® sprayer is 4-1/4 inches and comes equipped with a strainer to keep large particles out.

The diaphragm pump and other key seals are made of Viton ® for resistance to harsh chemical and abrasion. An advantage with this backpack sprayer is the diaphragm pump that can handle small particles and still resist wear and tear. The sprayer diaphragm is actuated by the connecting rod and the small internal pressure chamber reaches the operating pressure more quickly. The pump is capable of reaching up to 60 PSI.

The sprayer comes equipped with a 4 Ft high pressure hose and a 28″ wand. The wand has an easy to operate shut off valve with a lock feature. The backpack sprayer pump lever is adjustable to allow the operator to use either their right or left hand.

The backpack design and the padded straps make carrying 4 gallons of liquid easier. The padded straps have pull tabs for easy adjustment on your back.
