    • A pumping device is disclosed, comprising: i) an impeller; ii) a pump housing, which at least partly surrounds an inner region, with an inlet and an outlet, wherein the impeller is provided in the inner region of the pump housing; wherein the pump housing comprises an assembly made up of a first hollow body and a further hollow body, at least partly surrounding the first hollow body on the side facing away from the inner region; wherein at least 60% of the surface of the side of the first hollow body that is facing away from the inner space is connected to the further hollow body, with respect to the surface of the side of the first hollow body that is facing away from the inner space, wherein, with a further surface of the first hollow body, the pump housing is facing the inner region; wherein the further surface of the first hollow body that is facing the inner region of the pump housing has a hardness of at least 330 HV, wherein the further hollow body has a metal content of at least 50% by weight, with respect to the total mass of the further hollow body. Furthermore, a method for producing a pumping device is described. Also described is a pump housing produced by the method according to the invention and also a housing that has the same features as the pump housing of the pumping device according to the invention.

    • The invention concerns a method for sorting balls to separate those having a sphericity defect from spherical balls, comprising: - depositing the balls to be sorted on a support (1) having a conical surface (11), the axis (11 a) of said cone being vertical; - applying vibrations to said support (1) to cause the non-spherical balls to follow an upward trajectory on the conical surface (11) whilst the spherical balls roll downwards on said surface; - evacuating the balls having a sphericity defect via an orifice (13) arranged in the upper part of the support; - evacuating the spherical balls via an orifice (14) arranged in the lower part of the support. The invention also concerns a device for implementing said method.
    • 本发明涉及一种用于分选球以将具有球形缺陷的球从球形球分离的方法,该方法包括: - 将待分选的球沉积在具有圆锥形表面(11)的支撑件(1)上,所述轴(11a) 锥体是垂直的; - 向所述支撑件(1)施加振动以使所述非球形球沿着所述圆锥形表面(11)上的向上轨迹行进,同时所述球形球在所述表面上向下滚动; - 通过布置在支撑件上部的孔口(13)排出具有球形缺陷的球; - 通过布置在支撑件下部中的孔口(14)排空球形球。 本发明还涉及用于实现所述方法的设备。
