The Verderair high pressure series is especially suitable for charging filter presses. The higher the pressure that is achieved, the dryer and therefore lighter the filter cake will be. This results in cost savings of disposal of the filter cake. Verderair high pressure pumps are constructed to be self-regulating for filter press feeding. The high pressure pumps can run dry safely, will not over pressure, has an excellent self priming capability and is very easy to start up.

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 availble for ATEX, food and pharma applications.
