Abstract

The invention relates to a pump arrangement comprising a multi-part housing (1), in which a vane pump (2) is accommodated. Said vane pump (2) comprises a rotor (4) which is rotationally fixed to the drive shaft (3), an eccentric ring (5) surrounding the rotor (4) and vanes (7) which are accommodated in a radially displaceable manner in the rotor (4) slots (6) which can move radially. A vacuum pump (8) which can be driven by the drive shaft (3) is also arranged in the housing.
