Abstract: A method of controlling a gear pump comprising two meshing gear wheels (11, 12), wherein the two gear wheels (11, 12) are driven via respective shafts (2, 3) each by a drive unit (7, 8). A current position of the one gear wheel (11, 12) is determined with respect to the current position of the other gear wheel (12, 11), and the current position of the one gear wheel (11, 12) is continuously adjusted with respect to the current position of the other gear wheel (12, 11) according to specified predefined operating conditions.

Abstract: An arrangement including a gear pump (1), comprising a pump housing (10), two meshing gear wheels (11, 12) contained in the pump housing (10) and two shafts (2, 3) which are operatively connected to the gear wheels (11, 12) and extend through the pump housing (10), is disclosed wherein the two shafts (2, 3) are each operatively connected to respective drive units (7, 8). The arrangement includes a coupling unit (22) for compensation of eccentricities between the drive unit (7, 8) and the respective shaft (2, 3) is arranged between each gear wheel (11, 12) and drive unit (7, 8) and that a rotary encoder/sensor unit (24, 25) is arranged between the center of the gear wheel and the center of the respective drive.
