The present invention relates to an arrangement 1 which works on centrifugal force principles and comprises a member 2 pumping medium fractions and a part 3 which tapers towards the medium-pumping member and feeds medium fractions. The medium-feeding part 3 has an inlet 4 for the medium 5 intended for pumping and an outlet for the medium intended for pumping. The outlet 6 is arranged close to the medium-pumping member 2. The medium-pumping member 2 consists of two units 7, 8, each having an inlet 7a, 8a interacting with the outlet 6 for the medium- feeding part 3 and each having outlets 7b, 8b separate from one another. The medium consists of particles suspended in liquid, such as crushed material or sand particles suspended in water. <IMAGE> |
