The Roundup 190367 backpack sprayer features an exclusive internal No Leak Pump that keeps your back and clothing dry. The paddles keep liquids, powders, and water-soluble solutions mixed, in solution, and ready to spray. Also the pump features Viton seals that can be easily changed within minutes without tools (up to 7x faster than the leading competitor). The premium shut-off offers a comfort grip, lockable trigger to prevent hand fatigue, and a removable in-line filter to reduce clogging.
