Air operated double diaphragm (AODD) pumps are suitable for a wide range of applications. They have a high abrasive resistance and withstand aggressive chemicals including acids, oils, solvents, paints, sludges and even media containing solid particles such as found in waste water. These pumps can also be used for transferring powders. All the pumps are self-priming and the capacities and pressure can be easily controlled.
The pump casing in contact with the fluid is made of PE (polyethylene), PE conductive, PTFE (polytetrafluoroethylene), PTFE conductive, AISI 316, aluminium, cast iron. The Hygienic Series AODD pumps from AISI 316L material are specifically designed to meet the demands for the food, beverage, pharmaceutical and cosmetics industry.
