If you need a sprayer that can handle use with common abrasive agricultural chemicals, the Solo 475-B Backpack Sprayer will do just that.
Designed for commercial use, the Solo 475 B can be used to spray weed and insect control products, such as herbicides, pesticides, and insecticides, on plants and vegetation. The sprayer can also handle use with fertilizers and liquid formulations, as well as harsh, abrasive chemicals such as bleach, and wettable powders that may otherwise cause damage to a piston pump.
That is so because the Solo 475 has a connecting-rod activated diaphragm pump that consists of a high-quality Viton that resists harsh chemicals and abrasion. The diaphragm pump is able to pass small abrasive particles without damaging the pump assembly. Only the chemical-resistant parts come in contact with the spraying formula, ensuring years of unproblematic spraying.
Its diaphragm pump enables the sprayer to produce a pressure up to 60 PSI, which results in bigger droplets with less spray drift.
Includes a 28" long spray wand with shutoff valve and 4' of high pressure hose for hard-to-reach spraying areas; thick padded shoulder straps for user comfort; and 3 spray nozzles (adjustable, flat fan, and cone).
