This system has been designed for testing diesel high pressure common rail pumps. The test bench simulates the mechanical drive by a servo motor as well as the hydraulic low and high pressure circuit. It measures the delivery flow capacity, the high-pressure and the torque depending on fluid temperature, rotation frequency of the pump and drive current of the volume control inlet valve. Thus, the efficiency of the pump, among other things, is determined at different operation points. The test bench is designed for semi-automatic operation with manual loading and unloading and automatic test sequence.

This mobile system is designed for monitoring and calibration of flow rate sensors in existing test benches. The trolley has three flow rate sensors which are different in their measurement ranges. These sensors can be connected serially to the flow rate sensor which is to be calibrated by means of non-interchangeable quick couplings. In order to deaerate the measuring system, the lockable and adjustable pneumatic regulator as well as the waste tank with automatically controlled inlet valve can be used. The setting, controlling and handling of the test run are carried out by the integrated PC as well as the hand-held control panel. At the end of a test run a test report is created automatically.
