As part of Service Pump’s free training opportunities, we recently offered a virtual Centrifugal Pump Installation, Maintenance, and Troubleshooting course. We’ve broken down key topics from that course in this blog series, which shares expert strategies to ensure proper installation and tips to maximize the life of your pump.
Even with a perfect installation, regular pump use will result in wear and tear on your equipment. Performing routine maintenance can help extend the life of your centrifugal pump. SPS Vice President Danny Spears and Sales Manager Charlie McKenzie share step-by-step instructions for performing routine centrifugal pump maintenance.
How to Perform Routine Centrifugal Pump Maintenance
To start, check the packing and adjust or replace it if necessary. Inspect the mechanical seal and ensure proper adjustment, and then recheck the pump’s alignment. Document flow, pressure, and amperage, and compare these readings to the baseline measurements. This ensures your pump is working at optimal levels. If the pump performs below the baseline numbers, you may need to go back and make additional adjustments.
Next, ensure the bearings in the pump and motor are properly lubricated using either grease or oil. For best results, refer to the owner’s manual before lubricating the pump. It’s essential to stay consistent with the type of lubricant, and not mix and match grease and oils.
During your annual maintenance checks, ensure no rust or deterioration is present on your pump. Check the wear on the flexible couplings, and ensure the shaft and coupling guards are in place and securely fastened. Check and retighten all fasteners that bolt down the pump and motor.
Finally, have a qualified electrician check for loose electrical connections. Retighten any loose connections as necessary.
