Smith Performance Sprayers NL403 Backpack Sprayer


The last, but certainly not least, option on our list is the Smith NL403 No-Leak Backpack Sprayer. With the inclusive of Viton seals throughout, there is no risk of leakages from the tank or from the wand – as it features a 5 psi non-drip check valve with an integrated filter which stops any rogue drips when it is not in use. In addition to this, the wand is made from 21 inches of stainless steel and is incredibly hard wearing. 

This sprayer can reach a stream of an impressive 30 feet and 65% higher pressure than most other leading diaphragm pump backpacks on the markets. You can use it with a multitude of liquids, powders and water-soluble solutions, thanks to its built-in agitator.
