Abstract: A method for detecting faults or operational parameters in a pump assembly by use of a handheld communication device is described. The pump assembly includes an electric motor and a pump, wherein the pump assembly or electric motor has at least one rotating shaft The method comprises the steps of: a) measuring a sound signal emanating from the pump assembly by use of a microphone connected to or implemented in the handheld communication device, b) processing the measured sound signal, and c) recognising one or more sound emanating condition including any possible faults by way of the processed sound signal. The app automatically repeats at least steps b) and c) for a plurality of preselected frequency ranges in order to detect different fault states.

Abstract: A method for authorizing a data communication between an electronically controlled pump assembly (1) and an operating device (12), configured for wireless communication with the pump assembly (1), operating using an external server (10) connected to a data network. The method includes transferring the installation location data (GPS 1) of the pump assembly (1) to the server (10) via the data network. An identification code of the operating device (12) and the location data (GPS 2+3) of the operating device (12) are then transferred to the server via the data network. On the server side, it is examined whether the operating device (12) is envisaged for data communication with the pump assembly (1), and whether the operating device (12) is located in a predefined spatial region (A) to the pump assembly (1). Subsequently a data communication is enabled or blocked, for a time.

Abstract: A method for detecting faults or operational parameters in a pump assembly by use of a handheld communication device is described. The pump assembly includes an electric motor and a pump, wherein the pump assembly or electric motor has at least one rotating shaft The method comprises the steps of: a) contactless measuring a sound signal emanating from the pump assembly by use of a microphone connected to or implemented in the handheld communication device, b) processing the measured sound signal, and c) recognising one or more sound emanating condition including any possible faults by way of the processed sound signal.
