Measurement guide for replacement seals

By Chemical Engineering |

Mechanical seals play a pivotal role in the chemical process industries (CPI). As the sealing interface between rotating process equipment and the materials contained inside, these devices prevent product leakage and fugitive emissions, while permitting process machines, pumps and compressors to operate at ever-increasing pressures, vacuums, temperatures and speeds. Even the most basic mechanical seal is a complex assembly. Correct measurement of the machinery for replacement seals can be an underappreciated aspect of maintenance planning. The following steps outline basic procedures and considerations involved in measuring machinery for replacement seals. Measuring for shaft seal replacement Step 1. Shaft diameter Measure the shaft diameter (ø) where the replacement seal will be installed. It’s important to actually take a measurement of the shaft and sleeve, rather than relying on dimensions from the machinery’s blueprints. The shaft diameter can vary slightly at different points along its length, so take the measurement where the seal will be positioned. This may mean removing the existing seal, or at least sliding it out of the way. The shaft may be worn or fretted, so…
