Q What can be done if the tubing is leaking? A It is possible to push a wire ferrule over the attached tubing end to clamp it tightly to the connector. The ferrule doesn’t have to be crimped. If crimping is required for a very strong fixation, please make sure that the ferrule does not create such a deformation that a gap
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 begins to create air bubbles
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 value. So far we have
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 order to ensure stable pump
