Now with a piston pump, operated by a maximum-leverage pump handle, which can be mounted on either side of the tank. Pump chamber holds pressure, so minimum pumping effort will produce consistent pressure (maximum pressure is 90 psi) for a wide range of spraying tasks.

  • High-impact, UV resistant polyethylene tank is made for hard field use.
  • Leakproof lid has a one-way valve that lets air enter the tank (to prevent vacuum build-up) but keeps the spray material in.
  • Large filler port with its removable strainer, permits quick on-site refills without a funnel. Dirt and large particles are further screened by the built-in filter in the piston chamber.
  • 22" spray wand is reinforced with fiberglass and comes with a trigger sprayer, quality shut-off valve, and 4 nozzle options (fan, hollow cone, plastic adjustable and jet stream spray patterns).

We especially recommend the brass adjustable spray nozzle.

Over 5 Years and Going Strong

I've had this sprayer for several years and I've been very pleased with the quality. I've never had a leak and the sprayer is easy to pump and easy to fill. The only thing it does that I don't like is that the back pack straps are held on by clips that occasionally become unclipped as you put it on. It's a bit of the pain to re-clip the clips while putting on a full sprayer. Over all though, this is a great tool that will last many seasons. Mine is over 5 years old and going strong.
