| 20110297388 | METHOD AND DEVICE FOR PRESSURE REGULATION OF A WELL - A method for the pressure regulation of a well ( | 12-08-2011 |
| 20110150689 | OUTER ROTOR OF A PROGRESSING CAVITY PUMP HAVING AN INNER AND AN OUTER ROTOR - An outer rotor of a progressive cavity pump comprising at least one inner helical rotor with Z external thread starts and at least one adapted outer rotor with a helical cavity with Z+1 internal thread starts, characterized in that at least an outer rotor ( | 06-23-2011 |
| 20110150687 | PROGRESSIVE CAVITY PUMP WITH INNER AND OUTER ROTORS - The invention relates to a progressive cavity pump comprising at least one inner rotor ( | 06-23-2011 |
| 20100239446 | PROGRESSING CAVITY PUMP WITH SEVERAL PUMP SECTIONS - A progressing cavity pump comprises at least an inner pump rotor enclosed by at least an outer pump rotor so as to collectively form one or more, in principle, separate pump cavities which, according to known geometric principles, will be moved axially through the pump upon bringing the rotors into coordinated rotation. At least two pump sections are disposed therein, each of which comprises one outer pump rotor and one adapted inner pump rotor. The outer pump rotors of all pump sections are fixedly supported and arranged along the same axis, wherein all the inner rotors are supported in fixed positions relative to a pump casing of the pump. The outer rotors of all pump sections are driven by the same motor via at least one differential arranged to allow each pump section to rotate at a mutually different rotational speed. | 09-23-2010 |
