Definitions

  • the receptacle is formed by a bore in the housing.
  • the second sensor channel can advantageously lead through a bore forming the receptacle, whereas according to an advantageous development of the invention the first sensor channel is arranged in continuation of the bore forming the receptacle, preferably in alignment with it Recording is designed as a stepped bore.
  • centrifugal pump assembly consists of a centrifugal pump 1 with an electric motor 2 connected thereto, which drives via a shaft 3 in the pump housing 4 rotatably mounted about a rotation axis 5 gyro 6.
  • the electric motor 2 is shown for clarity purposes without terminal box and the engine electronics therein including the electronic speed controller.
