A screw spindle pump for the delivery of fluid media with a pump housing having an inlet channel with a first longitudinal axis, an outlet channel with a second longitudinal axis, a first drive spindle with a third longitudinal axis, and a second driven spindle. The spindles each include a profiled section between the inlet channel and the outlet channel, wherein the profiled sections of the spindles are engaged at least partially with one another and form, with the pump housing between the inlet channel and the outlet channel, a delivery section parallel to the longitudinal axis of the drive spindle with delivery chambers for the fluid medium. The second longitudinal axis of the outlet channel is disposed at an obtuse angle to the delivery section in the pump housing. The invention also relates to a method for operating a screw spindle pump.

Screw pump

A screw spindle pump constituted by at least two parts is disclosed. The first part includes a housing and at least one spindle system disposed in the housing and capable of being driven in a rotational manner. Furthermore, a pressure region disposed downstream of the spindle system and at least one outlet opening which is connected to the pressure region, the outlet opening discharging the delivery medium out of the pressure region. The second part includes at least one low-pressure chamber disposed upstream of the spindle system and at least one inlet opening for the delivery medium into the low-pressure chamber. The first part and the second part are coupled together, preferably in a rotational manner, so that they can assume at least two different relative positions.

Screw pump with at least two parts

A submersible pump assembly for use in a borehole, including a screw pump and/or an eccentric screw pump with a longitudinal axis. The submersible assembly further includes a drive and a bearing arrangement for taking up and diverting the axial and/or radial forces arising during the operation of the screw pump and/or eccentric screw pump. The drive is disposed, via a first coupling rod, at one end of the screw pump and/or eccentric screw pump and the bearing arrangement is assigned, via a second coupling rod, to the opposite end of the screw pump and/or eccentric screw pump along the longitudinal axis.
