Product
Information

solo® Standard Backpack Sprayers . . . our #1 selling sprayers

  • Disease control on animals
  • Weed, insect and disease control on plants
  • Spot spraying
  • Industrial vegetation control
  • No corroding of pump components

solo® backpack sprayers are designed so only chemical-resistant parts come in contact with the formula being sprayed. As a result, you'll have years of trouble-free spraying. Piston Pump sprayers allow a wider range of applications than diaphragm pump models. Not recommended for use with abrasive sprays or wettable powders because these substances can score the piston and cylinder of the pump, causing leaks and lowering the life span of the sprayer. Maximum pressure of 90 p.s.i. can be reached by replacing the pressure control valve with an optional plug. Tanks are made of high-density, UV-stabilized polyethylene with high-impact strength and excellent resistance to chemicals and stress. Nylon web straps are padded at the shoulders. Pump handle is adjustable for left- or right-hand operation. Supplied with two spray nozzles which provide three different spray patterns. Flat spray nozzle is recommended for general area spraying. For spot spraying, the conical nozzle provides a cone-shaped spray when used with the swirl plate and a pin-stream spray without the swirl plate. Large 4" opening with strainer allows fast and safe fillings. Features a handy interlock device for continuous spraying. 4 gallon sprayer. Weighs 11 lbs. empty. USA made.

Comments about Solo Backpack Sprayer -- 4-gal. Piston Pump:

I bought this a month ago used 1 tank, brought out today to use for 3 1/2 tank fulls and had the snap break on one strap and the adjustment buckle break on the other strap. I was very diappointed as the one it replaced that I garage saled when I moved never gave me any trouble, I used it for many years.

Comments about Solo Backpack Sprayer -- 4-gal. Piston Pump:

We get a lot of use out of these before we have to rebuild it. (easy to rebuild under 15 minutes)Should be cleaned if you let it set for any length of time.Might suggest replacing the plastic spray tip with a brass one.
