Claim 12:
13. A method of detecting a leaked drive fluid in a pump comprising:
collecting, in a buffer tube positioned in or on a pump cylinder, drive fluid leaked from a drive of the pump, wherein the pump cylinder comprises a seal adaptor that connects the pump cylinder to a drive housing that includes the drive, and a channel extends from the buffer tube into a portion of the pump cylinder and is offset from a pump chamber defined by the pump cylinder, so that the channel is configured to direct the leaked drive fluid that is leaking from the drive adjacent the seal adaptor toward the buffer tube and prevent the leaked drive fluid from entering the pump chamber defined by 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; and
generating an alarm when the leaked drive fluid reaches the maximum level.
