Abstract

A booster pump comprises rotors which are made up of a number of multi-lobed rotor elements 11a, 11b, 11c, 11d, 21a, 21b, 21c, 21d, the rotor elements being carried by a common rotary shaft 4a, 4b passing through a common axis of rotation, each rotor element 11a, 11b, 11c, 11d, 21a, 21b, 21c, 21d being rotationally angularly displaced with respect to the or each adjacent rotor element.
