Abstract:
The invention relates to a pump module, a base pump module and a pump system comprising a pump module and a base pump module. The pump module (1) according to the invention comprises a pump channel (5) and a valve chamber (12) connected to the pump channel (5), a fluid being pumpable through the pump channel (5) and the valve chamber (12), a first wall section (13) of the valve chamber (12) being flexible, and the pump module (1) having a mobile valve body (14) that is arranged in the valve chamber (12), the valve body (14) being configured to assume a rest position in which the valve body (14) obturates the valve chamber (12) from the passage of the fluid, and being configured to assume a position of actuation in which the valve body (14) allows the fluid to flow through the valve chamber (12). The valve body (14) can be brought into the position of actuation by way of a deformation of the first wall section (13) to allow the fluid to flow through the valve chamber (12).
