Root cause analysis of pump valve failures of three membrane pump systems
conference paper
This paper will present the root cause analysis and the solution of fatigue failures of the pump valves of three membrane pump systems installed on a chemical plant of Momentive in Pernis, the Netherlands. The membrane pumps were installed approximately 30 years ago. Each system has encountered fatigue failures of the membranes, valve plates and springs on the discharge side in the past. The Mean Time Between Failure (MTBF) was in the order of approximately 2 to 3 months. Many different modifications have been investigated by the operator but unfortunately without success. A reduction of the costs involved with each shut-down and repair was necessary and after many years of trying different measures to mitigate the problems, it was decided to perform a thorough analysis to find the root cause of this issue.
