DELLMECO air operated diaphragm (AODD) pumps (DM20/75) 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.
They can be ‘dry run’ without damage and using conductive plastics can be made explosion proof for solvents, alcohols and other volatile liquids without the risk of the build-up of electrostatic charge..
The pumps also require no lubrication and are of the so-called “Stall-Free Design” that makes them always start even at low air pressure and low air supply.
All DELLMECO aluminum and cast iron pumps are ATEX (explosion proof) approved.
