Gilardoni’s gear pumps series double monobloc  “VMD” DOUBLE MONOBLOC represent the natural evolution of the series VM of which retain the basic characteristics of being mounted on horizontal pipe, vertical, at any angle. This is the coupling of two pumps VM that allows a wide use of employment in special situations, in which the application of a standard pump denotes the limitations of use. The pump series VMD can be employed in the transfer of two different fluids with the use of only one motor, for obtaining a double flow or fluid used to clean the impurities, through a process of filtration, without any interruption of the productive cycle.
