En membranpumpe med dobbeltport (med split manifold) gør det muligt for pumpekamrene at fungere som to forskellige pumper. Adskillelsen af kamrene tillader pumpning af to forskellige væsker samtidigt eller blanding af to væsker. En membranpumpe med split manifold kan for eksempel overføre UV-maling i trykpressen og tømme UV-lakrester fra drypbakken under den samme maskine. Kapaciteten af begge membrankamre er altid den samme, så pressen vil aldrig løbe over, og cylindrene absorberer malingen fuldstændigt.

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.
