Use the Sprayers for herbicides, insecticides, fungicides, fertilizers, stains, sealers, oil-based products and solvent-based products. No. 111415 resists chlorine better than the other models, thanks to its special O-ring construction. No. 200700 combines the safety of a factory sealed diaphragm with the high pressure of a piston. The patented sealed pump module delivers 150 psi by incorporating a piston into the diaphragm pump mechanism. This High-Pressure Backpack Sprayer's pump module generates pressure faster, saving time and effort. Engineered to last, each pump module is individually pressure tested prior to assembly.

Designed for comfort, convenience and easy operation, professional features include: exclusive swing back solid steel pump handle with locking pin that allows fixing the handle in pumping position or out of the way for storage or transport; oversized, 6"W mouth with strainer for faster filling with less spillage; built-in carrying handle makes transporting and handling easier; 4-gal. UV-treated polyethylene tank and chemical-resistant polyester straps; professional brass nozzle adjusts from stream to mist. Nos. 139514 and 172632 High-Pressure Backpack Sprayers add jet agitation, which enables you to spray wettable powders in addition to liquids. No. 172632 also has Viton® seals and a Viton diaphragm to allow you to spray chlorine-based liquids plus stains and sealers.
