How to maintain axial flow pumps
Axial Flow pumps require routine maintenance which consists of:
• Lubrication of the bearings.
• Inspection of the seal.
• Performing a vibration analysis.
• Monitoring the discharge pressure.
• Monitoring the temperature.
As well as this they also require routine inspections which consist of:
• Checking the level and condition of the oil through the sight glass on the bearing frame.
• Checking for unusual noise vibration, and bearing temperatures.
• Checking the pump and piping for leaks.
• Analysis of the vibration
• Checking the seal chamber and stuffing box for leaks.
Further Axial Flow Pump maintenance
- Axial flow pumps have a rather narrow safe operating envelope, which is close to a given pump’s Best Efficiency Point (BEP). Operating the pump outside of this range may result in higher energy consumption, vibration, noise, accelerated wear or pump failure
- Axial Flow Pumps tend to be low-speed application requiring special motor designs. Synchronous motors should be considered, where applicable, to reduce the impact on
the electrical system.
If the pump performance does not satisfy your process requirements, and the process requirements have not changed, then perform these steps:
- Disassemble the pump.
- Inspect it.
- Replace worn parts.
