The redesigned Verderair Hi-Clean limits the number of tri clamp connections which come into contact with the fluid which simplifies the disassemble and assemble of the pump and therefore also limits the risk of contamination.The pump is able to create up to 9,1m suction lift, has self-priming capability and can dry run without damaging the pump.

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.
