The Graco 652859 Husky 3300S SS/CR/CR/A is a heavy-duty 3-inch air-operated double diaphragm pump designed for high-volume industrial fluid transfer with strong chemical resistance and reliable performance.
The Graco 652859 Husky 3300S SS/CR/CR/A is a heavy-duty air-operated double diaphragm (AODD) pump designed for high-volume industrial fluid transfer. This pump is commonly integrated into large fluid handling and processing systems where reliability and chemical compatibility are important.
The Graco 652859 Husky 3300S is a 3-inch stainless steel air-operated diaphragm pump engineered for demanding industrial environments. It uses compressed air to move fluid through dual diaphragms, allowing safe pumping of abrasive, viscous, or chemically aggressive liquids.
Its stainless steel fluid section provides excellent durability and corrosion resistance, while the CR (polychloroprene) diaphragms and seats provide reliable sealing and chemical compatibility. This design makes the pump suitable for continuous operation in high-volume production facilities.
