You no longer need both a piston and diaphragm pump sprayer. The NL400 No Leak Pump Backpack Sprayer features an internal piston pump with agitation paddles allowing you to spray both wettable powders and liquids. The internal pump ensures chemicals stay in the tank where they belong instead of leaking down your back. The deluxe harness has pressure dispersing 3” wide shoulder straps with a fully lined back cushion and lumbar support to ensure maximum comfort while on the job. Tested to over 1,000,000 pump cycles, 3X longer than the nearest competitor, this workhorse will not let you down on the job.
