Centrifugal Pump Maintenance Guide

Known for reliability and sturdy design, centrifugal pumps are often used in demanding operating conditions. Over time, the pump components begin to wear, causing a decrease in performance. If not appropriately addressed, this can lead to increased bearing or seal wear, vibration, excess temperature, cavitation, or failure.
A routine centrifugal pump maintenance program is essential to extending the life of your system and reducing operating costs. By setting a schedule to inspect, log, and repair pump components, routine maintenance provides a recorded maintenance history. The benefit of having a recorded centrifugal pump maintenance checklist can allow you to discover the source of the problem faster.

Our Recommended Centrifugal Pump Maintenance Checklist

During routine maintenance procedures, many components must be inspected to ensure proper performance and system longevity. To conduct comprehensive, full pump system inspections, you should examine bearing and lubricant conditions, shaft seal conditions, overall system vibration, and discharge pressure for the correct operating parameters. Use our recommended centrifugal pump maintenance checklist for routine procedures:

• Bearings & Lubricant: Monitor and record bearing temperatures, lubricant level, and vibration. System lubricant should be clear with no bubbling. If there is bubbling, more lubricant should be added to decrease the bearing temperature. If an increase in vibration is recorded, that may indicate upcoming bearing failure.
• Shaft Seal: Check mechanical seals for leakage, and during downtime, inspect the pump’s packing for adequate lubrication. If the packing appears compressed and dry, it should be replaced with new lubricant added according to manual specifications.
• Pump Vibration: The overall system vibration can be used to indicate imminent pump failure. If there is excessive vibration, it may be caused by a change in pump alignment, bearing failures, cavitation, or an obstruction in the suction or discharge lines.
• Discharge Pressure: By calculating the difference in pressure read by the suction and discharge gauges, you can determine the total developed head pressure of the pump. Confirm the reading is within the desired performance parameters.

It is critical to inspect components for signs of wear, damage, or leaks at least once a year. When the system is disconnected with the power locked out, check the following components for indications of failure:

• Check bearing frame and foot for cracks, roughness, scale buildup, rust, as well as pitting and erosion in machined surfaces.
• Inspect bearing frame tapped connections for dirt, remove foreign material, and inspect lubrication passages for blockage.
• Check the shaft and sleeve for grooves and pitting, bearing fits and shaft runout.
• Examine the casing for signs of wear, pitting, and corrosion, and also check gasket surfaces for irregularities.
• Inspect the impeller for wear, erosion, and corrosion.
• Check the frame adapter for cracks, warping, and corrosion damage.
• Examine bearing housings for signs of wear, corrosion, pits, and cracks.
• Check the seal chamber or stuffing box cover for pitting, cracks, erosion, corrosion, or wear with scoring or grooves on the chamber face.
• Inspect the shaft for evidence of corrosion, wear, and general straightness.
