Tech Tip: Pump Maintenance

Time is critical when equipment goes down. When a pump seal breaks, the pump is frequently opened on the floor and the parts are replaced. Although this practice can work when combined with thorough, regularly scheduled full maintenance programs, 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 critical to remove it from the line and fully disassemble. Check parts for excessive wear and replace all of the parts in the kits. Not only on the wet end, but inspect the motor shaft and motor as well. If the 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.
