Abstract

The invention relates to a pump for conveying a fluid. The pump comprises a pump housing (1) with at least one fluid inlet (35) for the fluid to be conveyed, with at least one pumping chamber (4), which has a flow connection to the fluid inlet (35), and with at least one fluid outlet (34), which has a flow connection to the at least one pumping chamber (4). It also has at least one diaphragm (2) for conveying the fluid, which at least partially limits the at least one pumping chamber (4), and at least one diaphragm actuating mechanism (3) connected to the at least one diaphragm (2) to actuate the at least one diaphragm (2). Furthermore, the pump comprises at least one coupling mechanism, which releasably connects the at least one diaphragm (2) and the at least one diaphragm actuating mechanism (3) to one another.
