The Verderair EODD pumps (Electric Operated Double Diaphragm pumps) combines all advantages of an AODD with the energy efficiency of an electrically driven pump. Unique is the automatic stalling of the membranes against a closed discharge.

Diaphragm Pumps

The Verderair diaphragm pumps are the best solution for transfer applications that require more than just fluid to be handled. The range is excellent for viscous or sticky media, slurry and solids. The Verderair diaphragm pump series offers diaphragm pumps, varying in material (metallic, non-metallic, conductive) to drive principle (electric, pneumatic). Applications are found in chemical industry, pharmaceutical industry, solar power industry, waste water treatment, ceramic slurry, and many more. Special models are available for ATEX, food and pharma applications.
