AODD pumps with 3/4 inch (19.05 mm) connection available in aluminum and stainless steel. The Husky 3/4-inch pneumatic positive displacement double diaphragm pumps have an external controller for remote control capabilities.
Graco recommends the installation of a fluid pressure relief valve at the pump outlet to prevent over-pressurization and rupture of the pump or hose. Use Fluid Pressure Relief Kit part number GR238428 for 716 aluminum Diaphragm Pumps.
Graco Husky Fluid Kits include the O-rings, Seats, Balls & Diaphragms for the specific materials in your diaphragm pump and can be found in our Parts Department.
