    摘要： A blade for an impeller comprises a blade with a front portion with a leading edge and a trailing portion with a trailing edge joined by spaced apart pressure and suction sides to form an exterior blade surface. The blade pressure side is formed from an outer envelope of a first blade profile aligned in a first position; and at least a part of the front portion of the blade suction side is formed by rotating the first blade profile around the leading edge to match an angle of the incoming flow at a lower flowrate condition of the impeller.

    摘要： An impeller for a centrifugal pump comprising a boss supported by a rotation shaft of a motor so as to be rotatable as a unit with the rotation shaft; and a plurality of blades that extend from the boss towards a radial direction outside of the boss, and that discharge liquid towards a leading end side thereof by rotating; wherein each blade comprises one side face that is a face on a first side in a rotation direction of the impeller and includes a projecting face that projects from a base end portion at a boss side of the one side face towards the first side in the rotation direction with respect to a line that connects the base end portion and a center of rotation of the blades.

    摘要： A centrifugal pump with a cutter mechanism has a toothed cutter auger affixed to an impeller, and a toothed cutter stator affixed to the volute casing. The auger is a rotor cutter preferably profiled radially to match the inlet geometry of the impeller vanes while extending along its central axis towards the pump suction. The auger is preferably radially concentric to the impeller and includes vanes numbered preferably to match the number of vanes on the impeller. The auger is affixed to the impeller, preferably with a lockscrew threaded into a common pump shaft. The radial profile of the auger essentially makes a continuous vane with the impeller, and prevents solids from hanging on the inlet vane tip or center void while providing a smooth flow transition into the impeller.

    摘要： The invention relates to a fluid pump or rotary cutter having at least one first element which can be brought from a transport state into an operating state by changing at least one mechanical property. Such a pump can, for example, be a blood pump for the medical, microinvasive area. The object of achieving a transition between the transport state and the operating state which is as comfortable as possible and in so doing leaving a freedom in the design of the corresponding apparatus, in particular of a pump, which is as large as possible, is achieved using the means of the invention in that the first element at least partly comprises a material or can be filled with a material or material mixture which passes through a chemical reaction, in particular cross-linking, or a crystallization for transition into the operating state.

    摘要： An impeller vane includes at least a first metallic core material and at least a first wear resistant material, wherein the hardness of the at least first wear resistant material exceeds the hardness of the at least first metallic core material. The impeller vane consists of a plurality of layers of the at least first metallic core material and the at least first wear resistant material, wherein the layers extend from a leading edge of the impeller vane to the trailing edge of the impeller vane and are arranged alternatingly throughout the cross section of the impeller vane. An impeller includes at least one of the above impeller vanes. The invention also relates to methods for manufacturing an impeller vane and an impeller having such.
