Abstract (en)

[origin: WO2014131393A1] The invention relates to a screw pump with at least two parts. The first part comprises a housing and at least one screw system which is arranged in the housing and which can be rotationally driven. It also comprises a pressure area arranged downstream of the screw system and at least one outlet opening which is brought into contact with the pressure area for guiding the pumping medium from the pressure area. The second part comprises at least one low pressure chamber arranged upstream of the screw system and at least one inlet opening for the pumping medium in the low pressure chamber. The first and the second parts are coupled together so they can assume at least two different relative positions, preferably so they can rotate.
