The Verderair Pure is designed for heavy-duty operation, harsh chemicals and severe process conditions, such as the manufacturing of photovoltaic solar panels, power stations, acids, solvents and petrochemical facilities. The Pure range is machined from a single block of virgin grade PE or PTFE. By machining the pump housing there are no welding points, which reduces material stress points and has superior handling properties against mechanical forces.

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.
