Time is critical when equipment goes down. When a pump seal starts to leak, the pump is frequently opened on the floor and the parts are replaced. This practice can be bolstered when combined with thorough, regular scheduled maintenance programs. Sometimes the workload can get so large that regular maintenance can slide, and then there are always fires to put out to add to the distractions.
When maintaining a pump, it is recommended to remove it from the line and fully disassemble it. Parts should be checked for excessive wear and all of the parts in the kits replaced. Not only on the wet end, but inspect the motor shaft and motor as well. If the motor bearings and shaft are not checked, the runout could be out of spec and the hundreds of dollars of new parts that are put in the wet end can be ruined within minutes—not to mention that those parts could end up in the product!
Also be sure to remove all rust from cast iron or carbon steel backplates and pump adapters. The rusting/oxidation process creates swelling that can impact the runout and create the same issues.
We recommend stainless steel pump adapters, as they are available for many pumps and motors, and will not rust.
