ABSTRACT:
For a medium pump (3) a mountable air pump (4) is provided. The stationary pump body (49) of pump (4) is fixedly connected to a member (8) provided for fixing the medium pump (3) to a reservoir (2). During the operating stroke a pressure chamber (50) of the air pump (4) permanently communicates with the reservoir (2) via the pump casing (15). Thereby pressure equalization is achieved. One and the same medium pump (3) can be provided with or without the air pump (4). When equipped with the air pump (4) the discharge of highly viscous media is significantly facilitated.
