Q What is the operation temperature range of the micropump mp6? A The data sheet mentions 0-70°C, but this is based on water. Zero simply because of ice creation, because ice has an expanding character and may destroy the pump. This is actually the cause for the storage concern here too. At a temperature of 70°C water […]
Q In which temperature ranges can the micropump be stored? A As long as the pump is stored without any liquid, i.e. water, there is no known limit to negative temperatures (Celsius). Positive temperatures are limited to ~130°C, regardless of liquid inside, as at that temperature the piezo ceramic and the applied adhesives will start to deteriorate.
Q Which maximum pressure can the micropump mp6 achieve? A With the current design of the mp6 the maximal pressure to achieve is limited by the actuator. It can generate only a certain force, once this force is reached the actuator doesn’t move anymore. Due to the tolerances of the actuator this force limit is no exact […]
Q What is the lowest flow rate that can be achieved with the micropump mp6? A The lowest flow rate is very dependent on the conditions in the customers test system. Generally a flow rate of about 20 µl/min for liquids can be achieved in most cases. With thorough optimization much lower rates can be achieved. In […]
Q Why do the micropumps mp6 generate a sound? A The piezo actuators are driven by the electronic controller connected to the micropump. When the driving signal has fast amplitude changes and the set frequency is in the range of human perception, a sound can be heard. If a sinusoidal signal is used within low frequencies (e.g. […]
