Claim 19:
20. A method of detecting a leaked drive fluid in a pump comprising:
collecting drive fluid leaked from a drive of the pump in a buffer tube positioned in or on a seal adaptor that connects a pump cylinder to a drive housing that includes the drive, so that the buffer tube may capture the leaked drive fluid that is leaking from the drive adjacent the seal adaptor and prevent the leaked drive fluid from entering a pump chamber of the pump cylinder;
defining a maximum level of the leaked drive fluid in the buffer tube by positioning a purge line on the buffer tube;
sensing, with a sensor, when the leaked drive fluid reaches the maximum level;
generating an alarm when the leaked drive fluid reaches the maximum level; and
adjusting the maximum level by adjusting a position of the purge line on the buffer tube.
