Definitions

  • the invention relates to a pump, in particular a fuel pump, having a pump casing, in which a pump chamber is formed, which has an inlet leading to it and an outlet leading away from it, having a pump impeller which is arranged in the pump chamber and is secured to a drive shaft, which can be driven in rotation and is mounted rotatably in bearings in the pump casing.
  • the thin coating can be applied with an exactly uniform thickness and thereby makes it possible to maintain low tolerances, so that a good build-up of pressure in the pump is ensured.
  • the two pump impellers 3 and 18 comprise phenolic resin.
  • the parts of the pump casing 7 are formed from aluminum.
  • the cover 6 has a coating of chromium nitride.
  • the partition 10 , the separating wall 23 and the bearing wall 27 are completely provided with a coating of chromium nitride.
  • the surfaces of the closure wall 29 and of the pressure port 26 around which the fuel washes are coated with chromium nitride.
