A dual port diaphragm pump (split manifold) allows the pump chambers to operate as two different pumps. The separation of the chambers allows the pumping of two fluids simultaneously or the mixing of two fluids with the pumping action. A dual port diaphragm pump can, for example, transfers UV paint in the printing press and empties the residue UV varnish from the drip tray under the same machine. The capacity of both diaphragm chambers is always the same so the press will never overflow and the cylinders absorb the paint completely.

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.
