摘要： 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.

摘要： A progressing cavity pump adapted for pumping of compressible fluids, comprising an inner rotor (1) having a number of thread-starts (Z) together with an adapted stator or outer rotor (2) provided with one extra thread-start (Z+1), wherein a number of, in principle closed pump cavities (6) are formed which are moved, during fluid conveyance, from the inlet side (A) of the pump to the outlet side (B) of the pump, at which position they become open outlet cavities (6c) exposed to the fluid pressure in a downstream pipeline, and wherein at least one passage is disposed between the outlet side (B) and the, in principle, closed pump cavity (6b) defined closest to the outlet side (B), wherein said passage is structured for intentional fluid back-flow from the outlet side (B) in a measured and approximately constant volume.
