<p>A method for circuit separation testing in a double gearwheel pump having two gearwheel pumps includes charging one of the two gearwheel pumps with pressure and measuring the pressure build-up in the charged gearwheel pump and/or the pressure-build up in the other gearwheel pump. The pressure build-up is preferably realized by the gearwheel pump itself. The gearwheel pumps have a common pump shaft and are preferably configured as hydraulic pumps of a hydraulic vehicle brake system with slip control. The method detects any leak at the leadthrough of the pump shaft through a partition wall between the two gearwheel pumps.</p> |
