Diaphragm Pump Sprayer: capable of producing up to 60 psi. The diaphragm is made of high-quality material for its resistance to harsh chemicals and abrasion and its long life expectancy. By design the diaphragm is able to pass small abrasive particles without damage to the pump assembly. Ideal for handling chemicals in wettable powder form, as well as liquid formulations. IMPROVED!! The diaphragm is now made with a new Tivilon ® material which can also handle bleach solutions. The spring in the shut-off valve is now stainless steel.
