Definitions

  • Such free-flow pumps are also referred to as vortical pumps whose capacity is transmitted from a rotating disk provided with blades, the so-called free-flow, to the flow medium.
  • Free-flow impellers are particularly suitable for conveying media mixed with solid admixtures, such as dirty water.
  • the free-flow impeller is a radial impeller which has a large passage for the solids contained in the pumped medium and is less susceptible to interference.
  • FIG. 3 is a plan view of the free-flow impeller as shown in FIG. 2;
  • the impeller 2 is arranged in a pump housing 15.
  • the front side of the free-flow impeller 2 has at its outer edge a distance A to the inside of the suction-side housing part 11.
  • the distance A is preferably defined as the distance that a normal, which is perpendicular to the suction side
  • Figure 5 shows a plan view of the impeller 2 as shown in Figure 4.
  • the distance 13 between the bundles 12 has an angle of Schaufelteiiung of 84 °.
  • the distance 14 of the blades 7 within the bundles 12 has an angle of 48 ° Schaufelteiiung.
  • the angles of the vanes between the bundles are by a factor of 1.75 greater than the angles of the vane pitch within the bundles 12.
  • the angles of blade pitch between the frets! 12 are thus not an integer multiple of the angles of the blade pitch within the bundles 12.
