The Graco 652906 Husky 3300 Diaphragm Pump is a high-capacity air-operated pump designed for demanding industrial fluid transfer applications. It delivers reliable performance for moving chemicals, coatings, oils, and other process fluids.
The Graco 652906 Husky 3300 Diaphragm Pump is a standalone industrial transfer pump designed to integrate with large fluid-handling systems. It is commonly installed in the following equipment and systems:
The Graco 652906 Husky 3300 is a heavy-duty 3-inch air-operated double diaphragm (AODD) pump designed for high-volume fluid transfer in demanding industrial environments. Powered by compressed air, the pump uses two diaphragms that move alternately to draw fluid in and push it out efficiently. This design eliminates the need for electric motors and makes the pump safe for hazardous or flammable environments.
This configuration typically includes a polypropylene center section combined with corrosion-resistant fluid components and durable PTFE diaphragms. The pump is designed to handle chemicals, coatings, oils, and other industrial liquids that require reliable and consistent transfer performance.
