A disc pump system includes a pump body (11) having a substantially cylindrical shape defining a cavity (16) for containing a fluid, the cavity (16) being formed by a side wall (18) closed at both ends by substantially circular end walls (20,22), at least one of the end walls being a driven end wall (22). The system includes an actuator (40) operatively associated with the driven end wall (22) to cause an oscillatory motion of the driven end wall (22) and an isolator (30) operatively associated with the peripheral portion of the driven end wall (22) to reduce damping of the displacement oscillations. The isolator (30) comprises a flexible material, which includes a radio frequency identification (RFID) tag (51) to store and transmit identification data associated with the isolator.
