Solo Hand-Pump Backpack Sprayer w/ Diaphragm Pump

The 475DLX is a virtually identical to Solo's popular 425DLX but it has a diaphragm pump mechanism in the place of the 425DLX's piston pump. In practical terms, this means that the 475DLX is better suited to abrasive materials, since the diaphragm completely isolates the spray material from the inner workings of the pump mechanism. The other major difference is that the diaphragm pump develops a lower maximum pressure (60 PSI vs 90 PSI for the 425DLX).

The Deluxe version features a folding handle for easier transport/storage, a pressure gauge, a four position regulating valve in the tank (15,30,45, and 60 psi) and a brass adjustable nozzle.

Additionally, the 475DLX has all of the features that make Solo backpacks our number one seller, year after year:

  • High-density polyethylene tank with ultra-violet inhibitors allows for unmatched durability and ultra-violet protection.
  • Large 4.25″ opening with filter basket
  • Shut-off valve and wand overall length of 28″ for hard-to-reach places
  • 4 ft. of high-pressure hose
  • Padded shoulder straps for greater comfort
  • The model 475DLX is capable of producing up to 60 psi, with its rugged connecting rod actuated diaphragm pump
  • Diaphragm is made of high-quality material for its resistance to harsh chemicals and abrasion and its long life expectancy
  • Diaphragm pump is ideal for handling chemicals in wettable powder form, as well as liquid formulations
