Q What are the best parameters to start the pump evaluation with the mp-x controller? A One big advantage of the mp-x controller is the possibility to set the whole range and combinations of all parameters: Frequency: 1 – 300 Hz, Amplitude: 1 – 250 Vpp; asymmetric Three different wave forms: Sine, Rectangular, SRS Using liquids, the […]
Q Did the micropumps pass an inspection before delivery? A All micropumps have to pass a final inspection before delivery. The test includes a performance test of the flow rate and the back pressure and is carried out using the settings as follows: Measurement conditions: Pump media: DI-water (gas for mp6-AIR and mp6-AIR-HP) Temperature: room temperature Controller: […]
Q How can the mp-x controller be operated? A Driving the micropump with the mp-x allows you to gather comprehensive results in short time. You will also be able to consider the sometimes complex interaction of micro- and macrofluidics with direct measurements of your system right from the beginning. Furthermore you will also be able to conclude […]
Q How does the pump perform when air bubbles occurs? A If the pumps behave erratically, it is very often caused by improper priming. If air is still inside, which is on the one hand compressible and on the other hand uncontrollable to know when such an air bubble starts to come out, the flow rate […]
Q What about the backflow behavior of the micropump? A The pumps are designed fluidically open, that means the passive valves inside the pump open on dynamic pressure changes. However, the valves are not completely leak tight and there will be a certain backflow – liquid or air – when a pressure difference exist. For […]
