Abstract

A pump seal leakage detection system () includes a leakage piping () including a collector pipe () and an air stream pipe (), a sensor () positioned at the air stream pipe (), and an air displacement device () for driving an air stream through the air stream pipe (). The collector pipe () includes an inlet port () that is connectable to a leakage centrifuge (), and an outlet port () into the air stream pipe (). The sensor () is configured to detect a leakage drop at the outlet port () of the collector pipe () or in the air stream pipe (). The air displacement device () is configured to blow a leakage drop off the outlet port () of the collector pipe () by an air stream towards an outlet port () of the air stream pipe ().
