I would recomend going to the Getting Started with DAQmx page and reviewing the information there. In LabVIEW, there is the DAQ Assistant on the Measurement I/O>DAQmx palette and there are numerous examples (Help>Find Examples) of using the lower level DAQmx functions.
If you were to provide a bit more information on what you need to do, it would help. For example, you have not said what type of signal you need to control this pump.
