<p>A lateral channel pump is disclosed which has a housing with a shaft sealed therein and a rotor secured thereto and a flow channel which starts from an intake port in the housing and leads to an outlet port in the housing via at least one lateral channel formed therein and via blade compartments of the rotor corresponding thereto. The blade compartments of a ring of blades of the rotor alternate in length, towards the centre of the rotor, between a long blade compartment and a short blade compartment and the associated lateral channel with its outer contour concentric with the centre of the rotor has an inner contour tapering helically towards the outlet port. The spacing of this inner contour from the shaft at the intake port corresponds to the spacing of a long rotor blade compartment from the shaft and, at the outlet port, it corresponds to the spacing of a short rotor blade compartment from the shaft.</p> |
