Chapin JetClean Commercial Backpack Poly Sprayer Dual Displacement Four-Gallon Dual Displacement Pump combines piston and diaphragm technology to provide increased pressure (well over 120 psi) and virtually eliminates piston leaks. Wide mouth six-inch opening allows for easy filling and cleaning/servicing of pump. Cap has a built in carry handle and wand clip. Large six-inch basket to catch (first stage filter) contaminants and debris when filling tank. In tank (second stage) 3-D removable filter. Self-cleaning JetClean design keeps 3-D removable filter from clogging from built up residue and debris. Swing-away pump handle can be left or right handed and swings away for more compact storage when not in use. Viton seals in the key, necessary areas for maximum chemical resistance.
