AODD pumps with 3/8 inch (9.52 mm) connection available in polypropylene and acetal. The Husky 307 positive displacement pneumatic double diaphragm pumps operate on as little as 20 PSI.
Graco recommends the installation of a fluid pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose. Use Fluid Pressure Relief Kit part number GR238899 for the Graco Husky 307 Diaphragm Pump.
