A pump is assembled, starting from a basic part having an inlet channel and an outlet channel, which terminate in a wall portion, by successively stacking a valve foil provided with an inlet valve and an outlet valve onto the wall portion, stacking an intermediate part having an inlet opening and an outlet opening onto the stack comprising the basic part and the valve foil, stacking an end part of a flexible material onto the stack comprising the basic part, the valve foil and the intermediate part, and securing the end part to the basic part. The pump is particularly suited for use in a personal body care appliance such as an electric shaver, depilating device or body massage device.
