Definitions

  • the basic design of the construction corresponds to that of a single-stage volute casing pump.
  • a suction cover 3 ensures an orderly axial flow against the radial or semi-axial impeller 1.
  • Brake ribs 2 reduce the pre-twist of the impeller 1 and create optimal inflow conditions for the impeller.
  • the pumped medium flows out of the radial or semi-axial pump impeller 1 into two (see FIG. 2) to four congruent spirals 5, which, depending on their number, have a 180 ° wrap angle for two channels, a 120 ° wrap angle for three channels and a 90 ° wrap angle for four channels.
