Abstract

The invention relates to a pump comprising a housing with an inlet and an outlet for the fluid to be delivered and comprising a first delivery rotor which is rotatably arranged within the housing and which forms a delivery chamber together with at least one section of the housing. The first delivery rotor is mounted on a support element (28) that is mounted within the housing in a movable manner in the axial direction of the first delivery rotor in order to adjust the delivery rate of the pump. According to the invention, the pump is characterized in that the support element (28) has a core (30) made of a duroplastic and a covering layer (32) made of a thermoplastic.
