Test Stand for Gear Metering Pumps - MarCheck

The Marcheck test stand allows a gravimetric or volumetric check of Flow.
Under defined conditions the gear pumps meter an oil against a preset counterpressure.
The metered quantity of each pump outlet will be measured one to another and in relation to the differential pressure. An electronic documentation is included. All tests are performed with a low viscous silicone oil (viscosity around 50 mPas) in order to get the highest accuracy of measurement. All other parameters remain constant while the outlet pressure will be adjusted to the required differential pressure. The quantity of oil at each outlet will be measured and the value electronically stored. These values are used to calculate the deviation of flow and the accuracy of metering for each outlet.
