Solo Inc 475-101 Backpack Sprayer 4 Gallon 60 Psi

Product Description

The SOLO INC 475-101 is a 4-gallon backpack sprayer built around a diaphragm pump system designed for field use with harsh chemicals, wettable powders, liquid formulations, and bleach solutions. The diaphragm is constructed from a chemical- and abrasion-resistant material, and the pump assembly is capable of passing small abrasive particles without sustaining damage. Maximum operating pressure reaches 60 PSI. The unit ships with a carry handle, padded nylon shoulder straps, a 28-inch wand with shut-off valve assembly, and a 4-foot high-pressure hose. Licensed pest control applicators, landscape professionals, and agricultural technicians are the primary installers and operators of this unit.

The 475-101 is suited for residential and commercial applications where chemical resistance and consistent pressure output are required. Typical use cases include applying herbicides, pesticides, fertilizers, and bleach-based disinfectants across turf, ornamental beds, hard surfaces, and agricultural plots. The large 4.25-inch fill opening with integrated filter basket speeds up filling and reduces clogging risk when mixing wettable powder formulations. The backpack configuration keeps the load centered on the operator for extended spraying tasks.
