Ahh "pump" as in push the chiller up and down...I thought you meant pump your chiller water into the wort!! It will help it chill faster, but yeah you'll probably still want to actually aerate also once its cooled and in the carboy. Apparently you need to be careful splashing too much while its still hot, but I don't know how viable of a concern this really is.
