Pump (100) with vanes (1) comprising a stator (2), a rotor (5) which is eccentric with respect to the stator (2) and rotating around the latter, each vane (1) exhibiting an angular offset with respect to a theoretical position for which this vane (1) would exhibit, together with all the other vanes (1) of the pump (100), a regular angular distribution with respect to a centre, the angular offset of the vanes (1) following a pseudo-random binary sequence, a "1" or "0" bit of this sequence corresponding respectively to an angular offset of a vane (1) in a first direction of rotation or in a second direction of rotation opposite to the first direction of rotation, this binary sequence being calculated via a sequence scrambling method Scrambler, this method being an additive method applying a pseudo-random binary sequence PRBS. |
