ABSTRACT:
A diaphragm pump with a driving motor has arranged in a case (5) at lease one drive (3) for transferring the pump movement to a pump diaphragm (4a). The case (5) of the diaphragm pump is essentially formed by at least one extrusion (6) configured to accommodate the drive(s) (3) and the driving motor (2). The extrusion (6) carries the driving motor (2), the drive(s) (3) and the pump head(s) (4). The extrusion (6) enables the pump case (5) to be specially dimensionally stable, to be manufactured at reasonable price, and has substantially smooth external surfaces. It is therefore easy to clean.
