    摘要: The pumping device comprises a pump driven by a motor having a stator and a permanent-magnet rotor located between polar expansions and connected to an impeller. A liquid suction duct and a liquid delivery duct are connected to the pump to define a hydraulic circuit. A reciprocating vacuum pump, for creating a negative pressure at the suction duct of the pump, has a resilient cylindrical element connected to a rigid cylindrical box-like element and defines therewith a chamber. The chamber has inlet and outlet valves connected to the hydraulic circuit through a poppet valve, and an arm-like member connected to the resilient element. An opposite end of the arm-like member supports a magnet located between poles of the stator of the motor, whereby to cause movement of the arm-like member and the resilient element for circulating fluid through the chamber via the inlet and outlet valves for priming the pump upon actuating the poppet valve.

    摘要: A filtering device, allowing to provide an effective filtering without either requiring particular efforts to the user or imposing him or her to operate in excessively hard positions, comprises a filtering element comprised between a first and a second supporting surface, the distance between the supporting surfaces being adjustable, so as to compress the filtering element by moving the supporting surfaces the nearer the other, and actuating device apt to modify the distance of the supporting surfaces. The actuating device is selectively connectable to a surface of the supporting surfaces in a such way that the actuating device can alternatively move unrelated to motion of the surfaces so as to be placed in an operative configuration or move integral to the surface so as to modify the distance between the surfaces in order to compress the filtering element.

    摘要: A skimmer (1) for aquariums comprises a base (10) and a container (20) which is provided with at least two lateral connectors (21, 22) which comprise a main connector (22) and an auxiliary connector (21). The skimmer further comprises a cup (30), in which the foam is collected. The base comprises at least four openings, a first opening (11) and a second opening (12) opening inside the container (20) and being connected to a third opening (13) and a fourth opening (14), respectively, so that the skimmer can operate at least in two different configurations: a first single-pump configuration and a second double-pump configuration.
