Zusammenfassung:In the case of a diaphragm pump (4), which is intended in particular as a dosing pump for use in biochemical engineering plants and which is provided with at least one self-closing inlet valve (22) and one self-closing outlet valve (21), additional lines, which in the nature of a bypass allow the valves to be circumvented, are provided for the purpose of carrying out a complete in-situ sterilisation of those areas of the pump in contact with the product. These additional lines can be shut off by means of valve spindles (32-35) and are each connected to an annular chamber enclosing the inlet and outlet valves.
