Verderair VA 20 Split Manifolds
A dual port diaphragm pump (split manifold) allows the diaphragms of the pump chambers to operate separately. 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 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.
