Abstract: The invention is a device (1) for controlling operational vibrations of a pump (2) or pump assembly arranged thereon. In some embodiments, it comprises a mounting plate (3) configured to have the pump or pump assembly arranged on a surface thereof. The device comprises at least one actuator (6) configured to switch between a first state in which it provides a connection between the pump or pump assembly and an associated carrying surface or between the mounting plate and the carrying surface, and a second state in which there is no such connection via the at least one actuator. Activation of the at least one actuator to switch between the first and the second states is controllable so that resonance characteristics of the pump or pump assembly during operation can be changed by the activation.
