Troubleshooting Tactics To Improve Pump Mean Time Between Repairs
MetadataShow full item record
Most pump reliability problems are rooted in basic errors that are made in the design, application, installation, maintenance, and/or operation of pumping systems. When the final, “correct,” solution to the system problem is determined, most of us look back at the simplicity of the solution and say “I knew that.” The solution is obvious when all the facts are known, and a proper root cause failure analysis is performed. Every process plant should assemble a task force to investigate pump reliability and repair quality. One of the primary goals of the task force is to establish quality criteria for process pumps that will drive mean time between repairs (MTBR) to as high as level as is practical. Seven years MTBR is a realistic target. Since time and space is not available, it is not the intent herein to compile a detail pump purchasing and repair procedure, but to outline the important subjects that should be addressed in such a document.
