The pump has a delivery device (10) moveable within a delivery chamber (3) for delivering gas, and a pressing device (30) for pressing housing parts (1, 2) against each other with a pressing force such that sealing surfaces (6, 7) abut each other and together form a sealing join that partially surrounds the delivery chamber in order to seal off the delivery chamber. One of the housing parts is movable relative to the other housing part against the pressing force in order to widen the sealing join to form a relieving gap such that liquid in the delivery chamber escapes through the gap. |
