A pump system and a method for pumping viscous or partially viscous media out of a borehole. The pump system includes a well pipe which is installed in the borehole and a motor which is coupled to an eccentric screw pump, the eccentric screw pump including one or more stators and one or more rotors which are received in the stator(s) so as to rotate eccentrically. One or more connection mechanisms fix the eccentric screw pump in the well pipe in a force-fitting and/or formfitting manner. For the purpose of removing the eccentric screw pump from the borehole, the eccentric screw pump is held by means of the one or more connection mechanisms with an axial freedom of movement.

Pump system for delivering viscous or partially viscous media from a borehole

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 progressing cavity gas pump with a stator which has a stator interior with an elastomeric inner surface as well as a gas outlet and a gas inlet, between which a pump delivery direction is defined, and with a rotor which engages with the stator interior, wherein below the stator, a lubricant reservoir is arranged which is connected via lubricant conduit devices to the stator interior. A progressing cavity gas pumping method using a progressing cavity gas pump, gas coming from a gas inlet is delivered with a rotationally driven rotor within a stator and through a stator interior having an elastomeric inner surface to a gas outlet and is compressed, and wherein from a lubricant reservoir below the stator, a lubricant supply to the stator interior takes place via lubricant conduit devices, and lubricant from the stator interior is recycled via the lubricant conduit devices into the lubricant reservoir.
