Abstract: A diaphragm pump, which comprises a pump body which defines internally at least one pair of pumping chambers which are connected, at the inlet, to at least one suction connector and, at the outlet, to at least one delivery connector of the pump; pumping chambers are delimited by respective diaphragms, which separate the pumping chambers from actuation chambers, which can be connected, alternately, to a source of compressed air; in the pump body an access opening to the pilot chamber is defined which is closeable by means of a closure element; the closure element comprises a main body made by molding and of plastic material and at least one plate-like element made of a material having, with respect to the sliding pad, a higher resistance to wear and a lower coefficient of friction than the plastic material.

Abstract: A system for controlling dispensing of fuel by a distribution facility, which comprises at least one dispensing unit, at least one mobile processing device, operated by a respective driver user, and a remote central processing device. The dispensing unit and the mobile device are mutually connectable via a short-range wireless communication network. The mobile device and the remote central device are mutually connectable via a telematic communication network; the mobile device comprises geolocation elements, configured to detect the geographical position where the mobile device is located, and an authorization verification module configured to enable the dispensing of fuel by the dispensing unit as a result of the connection between the mobile device and the dispensing unit, via respective short-range wireless communication modules, if the geographical position detected by the geolocation elements is located within a predetermined authorized geographical area.

Abstract: A system for circulating a liquid which comprises at least one pump, connectable to at least one pipe for the flow of a liquid and driven by at least one electric motor; sensors being provide for sensing at least two electrical parameters correlated with the operation of the electric motor and a processor which is functionally connected to the sensors and configured to determine, based on the signals provided by the sensors, at least one fluid-dynamic parameter correlated with the flow of the liquid through the pipe.

Abstract: A dispensing pump for fuel vending systems, comprising a pump body which forms internally a pumping chamber, which rotatably accommodates an impeller, functionally connected to a motor, and provided with an intake connector and a delivery connector, which communicate with the pumping chamber and can be connected to a fuel dispensing line; the pump body has at least one coupling portion for at least one auxiliary device of the dispensing line.

Abstract: An auxiliary device for pumps, comprising a device body which defines a conveyance duct, which can be connected to the delivery of a pump driven by an electric motor, and at least one accommodation portion for an electronic controller which is connected to at least one sensor for detecting at least one operating parameter correlated to the operation of the pump. The electronic controller is functionally connected to a short-range wireless communication unit which can be configured to communicate with to at least one mobile device operated by a user.

Abstract: A system for controlling the dispensing of fuel or the like in a vending apparatus, particularly for private use, comprising one or more dispensing assemblies, one or more mobile processing devices, and a central remote processing device, the mobile devices being configured to transmit data originating from the dispensing assemblies toward the central remote device. Each dispensing assembly comprises an electronic controller and dispensing element which comprise an electric pump, the electronic controller being configured to control electronically the electric pump of the dispensing element on the basis of the occurrence of an operating condition of the electrical and/or hydraulic type of the dispensing element of the dispensing assembly.

Abstract: A system for controlling the dispensing of fuel by a vending apparatus, comprising at least one dispensing assembly, at least one mobile processing device, and a central remote processing device. The dispensing assembly and the mobile device are mutually connectable by means of a short-range wireless communication network, while the mobile device and the central remote device are mutually connectable by means of a telematic communication network; the mobile device comprises mobile storage means, configured to store a list of driver users) who are registered and authorized at the dispensing assembly, and an authorization verification module, configured to enable the dispensing of fuel as a consequence of the connection between the mobile device and the dispensing assembly, by virtue of respective short-range wireless communication modules, if the driver user is registered and authorized.
