  • the kit further includes various replaceable drive means, each of which can be connected to each of the connectors and each of the pump drive shafts for driving the pump, and includes various replaceable seals which, with a selected connector, serve to close the rearward opening of the selected housing. wherein at least one connector and an associated seal are connectable between a selected housing and a selected drive to form the desired fixed centrifugal pump, and wherein at least one other connector and associated seal selectively and alternately replace the first mentioned one connector and the associated seal connectable for mounting between a selected housing and a selected drive to form a releasably coupled centrifugal pump.
  • the object of the invention is to further reduce the number of different components required for the production of, in particular, a standard centrifugal pump.
  • the object is achieved according to the invention in that at least two of the components are defined at least in two standards which relate to the industrial areas of water and chemistry, whereby the standards do not take into account Interface areas of a variety of the specified in the standards components of the same type are geometrically identical.
  • the interface regions of a plurality of the components of the same type defined in the at least two standards are geometrically identical, the interface ranges being disregarded by the standards, the individual series can be equipped with fewer components, namely Pump housing, housing cover, bearing carrier assembly, shaft, impeller, are manufactured across standards.
  • the interface area formed by the pump housing and the housing cover at their contacting surfaces is geometrically identical.
  • a further reduction in the number of different components can be achieved in that the interface area formed by the impeller and the pump housing at their interacting surfaces has the same geometric configuration.
  • the number of the plurality of components of the same kind can be further reduced if the interface area formed by the impeller and the housing cover at their interacting surfaces is geometrically identical.
  • the object of the invention is also achieved by a series of centrifugal pumps using a centrifugal pump described above.
  • a series of centrifugal pumps comprising a plurality of centrifugal pumps of different sizes, different materials and / or different applications with a small number of different components to be stocked provides.
  • a centrifugal pump for a fluid-carrying system wherein the centrifugal pump has a pump housing 1 with a suction port 2 and an exhaust port 3.
  • the pump housing 1 has an annular or cylindrical opening 4, which is closed fluid-tight by means of a housing cover 5.
  • the housing cover 5 rests against a bearing surface 6 at the opening 4 of the pump housing 1.
  • a projection 7 is formed, which surrounds the housing cover 5 partially and fixed in the radial direction.
  • Pump housing 1 and housing cover 4 form a geometrically identically formed interface region 8 at their contacting surfaces.
  • a bearing support assembly 10 is attached directly to the pump housing 1 and connected thereto and clamps the housing cover! 5 so tightly that it sits axially and radially immovable between the pump housing 1 and bearing support assembly 10. If necessary, for example, if the bearing carrier is to be thermally decoupled from the pump housing 1 or from the housing cover 5, the bearing support assembly 10 may additionally in the Fig. 1 not shown component, in particular a designated in the jargon as a component, have. Housing cover 5 and bearing support assembly 10 form at their contacting surfaces an interface portion 11 which is formed geometrically the same.

  • a motor not shown, is connected, which rotatably drives the shaft 13 about the axis of rotation A.
  • a split ring 20 is connected to the pump housing 1 in the interior of the pump housing 1 by means of a press fit.
  • Split ring 20 and impeller 13 are spaced apart, so that between gap ring 20 and impeller 16, a gap is formed.
  • Pump housing 1, in particular split ring 20 of the pump housing 1, and impeller 16 form at their cooperating, a sealing gap forming surfaces a geometrically equal Interface region 21.
  • the split ring 20 may also be integrated into the pump housing 1.
  • the split ring 20 may be attached as a race on the impeller 16 or integrated into this.
  • the housing cover 5 has a protruding into the interior of the pump housing 1 and coaxial with the axis of rotation
  • a ring portion 22, at its free end circumferentially another split ring 23 is arranged, which is preferably also connected by press-fitting with the housing cover 5.
  • a provided on the impeller 16 ring portion 24 at least partially surrounds the annular portion 22, in particular split ring 23, the housing cover 5, split ring 23 and impeller 13 are spaced apart, so that between the split ring 23 and the impeller 13, a gap is formed.
