The Stauff type SDMKR reversible flow device has been developed for rapid and accurate monitoring of hydraulic components and systems in mobile hydraulic systems. The design of the hydraulic tester allows combined measurement of flow, pressure, and temperature.

The device makes it possible for maintenance professionals to determine the performance of pumps, motors, valves, cylinders, and complete systems, and to ensure that these are functioning properly - directly on site or in the workshop. Potential weaknesses in the hydraulic system can thus be detected at an early stage, unscheduled machine downtime can be avoided, and maintenance costs reduced.

The operation of the hydraulic tester is based solely on mechanical principles: It can be used independently of any internal or external power supply, thus providing maximum flexibility.

Central to the device is a flow meter with a visual display and built-in thermometer, as well as a pressure valve, which makes it possible to increase the working pressure gradually and continuously up to 420 bar in order to provide a realistic simulation of regular machine operation. The pressure changes are documented by a stainless steel pressure gauge located at the inlet of the pressure valve. Two interchangeable burst discs act as internal safety equipment, effectively protecting the device against damage due to excess pressure.

Unlike other comparable devices on the market, the SDMKR also permits flow in the opposite direction. This enables hydraulic cylinders to be lowered during the system test, for example. In this case, however, the flow meter does not provide a display value.
