The disclosure relates to a conveyor device for at least conveying a fluid with at least one conveyor chamber, with at least one dimensionally stable conveyor chamber element that at least partially delimits the conveyor chamber and with at least one elastically deformable and, in particular, annular conveyor element, particularly a conveyor membrane, that delimits the conveyor chamber together with the conveyor chamber element and is arranged on the conveyor chamber element, wherein the conveyor element has at least one sealing extension that is designed integrally with a base body of the conveyor element and at least partially arranged in a sealing groove of the conveyor chamber element when the conveyor element is arranged on the conveyor chamber element.

A transfer pump. The pump is for displacing fluid and may generally include a housing; a pump including an impeller, the pump being disposed within the housing for creating suction to draw the fluid through the impeller; a motor for driving the pump; a battery operable to power the motor; and a sensor for sensing current drawn by the motor. The motor may be deactivated when the current drawn by the motor reaches a predetermined current value for a predetermined amount of time.

A conveyor device for conveying at least a fluid, comprises at least one conveyor chamber, at least one dimensionally stable conveyor chamber element formed separately from a housing in particular and at least partly delimits the conveyor chamber and at least one elastically deformable conveyor element, in particular a conveyor membrane, which together with the conveyor chamber element delimits the conveyor chamber and is arranged on the conveyor chamber element. The conveyor chamber element comprises at least one connecting piece for a fluid supply line adapter designed to differ from a tube, and/or at least one connecting piece, in particular an additional connecting piece, for a fluid discharge line adapter, which is designed to differ from a tube, said connecting piece/connecting pieces being arranged on a conveyor chamber element face facing away from the conveyor element, in particular on the exterior of the conveyor chamber element.

A rotary pump comprising a housing (1) defining an annular chamber with inlet and outlet ports (12;11) spaced apart around the chamber, a flexible annular diaphragm (3) forming one side of the chamber spaced opposite an annular wall of the housing (1), the diaphragm (3) being sealed at its edges to the housing (1), a partition (13) extending across the chamber from a location between the inlet and outlet ports (12;11) to the diaphragm (3). The diaphragm (3) is configured to be pressed progressively against the opposite wall of the housing (1) to force fluid drawn in at the inlet port (12) on one side of the partition (13) around the chamber and to expel it at the outlet port (11) at the other side of the partition (13). The outer face of the annular diaphragm (3) has a trough (40) at the part of the diaphragm (3) which faces the inlet port (12) and/or at the part of the diaphragm 3 which faces the outlet port (11).

Radial pump (1) comprising a stator (3) comprising an external stator (30) and an internal stator (32) defining an annular cavity (11) therebetween, and an impeller (5) rotatably housed between said stators (30; 32). The suction (7) is fashioned at a central portion of the internal stator (32), whereas the delivery (9) is fashioned at a radially external peripheral portion of the external stator (30). The impeller (5) comprises a plurality of deformable vanes (50, 51, 52) movable inside the annular cavity (11) and in slidable contact with the internal surface of the external stator (30). In every position of the impeller (5) with respect to the stator (3) at least two deformable vanes (51) are sealed in the portion of the annular cavity (11) between the suction (7) and the delivery (9) to isolate the delivery (9) from the suction (7). The impeller (5) is rotatable about a central internal axis (Al) offset with respect to the central external axis (AE) of the external stator (30), where the rotational eccentricity of the impeller (5) with respect to the external stator (30) determines a deformation of the deformable vanes (50, 51, 52) that contributes to the generation of flow rate of said pump (1).

A fluid transfer pump comprises: a housing, a pump unit, an electric motor assembly, a power supply mounting base, and a speed change mechanism, wherein the pump unit comprises an impeller; the electric motor assembly is used to drive the impeller to rotate around an axis of the impeller; the power supply mounting base is used to receive a power supply for supplying electricity to the pump unit; and the speed change mechanism is arranged between the pump unit and the electric motor assembly. The power supply mounting base is arranged in a power supply compartment; and the pump unit, the speed change mechanism, the electric motor assembly, and the power supply compartment are successively arrayed in an extension direction of the axis of the impeller.

A pumping system includes a universal adapter having a back end for attachment to a motor, a forward opening receiving area, an outer magnet assembly rotatable around the receiving area by a motor, and a forward mounting plate surrounding the forward opening receiving area and having mounting features adapted for attachment to the back cover of each of a variety of pump assemblies. The back cover includes mounting features for alignment with the mounting features of the forward mounting plate of the universal adapter.

A gerotor pump includes a pump head including a configuration of gerotors for pumping in operation a fluid medium from an input port arrangement to an output port arrangement, and a motor arrangement for providing mechanical power in operation for actuating the configuration of gerotors. The configuration of gerotors includes an outer gerotor and an inner gerotor that are operable to cooperate to entrap and propel the fluid medium from the input port arrangement to the output port arrangement. At least one of the outer gerotor and the inner gerotor are fabricated from a flexible material and/or are internally structured so as to exhibit a flexible peripheral exterior surface in operation. Moreover, the outer gerotor and the inner gerotor are loaded and/or are assembled together in a preloaded state, within the pump head, so that a gap formed between the gerotors whereat they mutually cooperate for entrapping and propelling the fluid medium is maintained in a flexibly compressed state when the pump is in operation. Optionally, at least one of the outer and inner gerotors is fabricated as a hybrid component including regions of a flexible material therein, and regions of an inflexible material therein. More optionally, the flexible material has a Young's modulus in a range of 1 MegaPascal (MPa) to 5 GigaPascals (GPa), and the inflexible material has a Young's modulus in a range of 2 GPa to 420 GPa.
