Ten tips for hygienic centrifugal (LKH) pump reliability
This supplied Alfa Laval guide covers routine service, visual checks, design conditions, shaft-seal protection and planned spares for LKH pumps.
- 1Service and maintain routinely
Routine service keeps the pump operating at its best and holds performance over time.
- 2Inspect visually
Regular visual checks catch wear early, when it is easier and cheaper to address.
- 3Schedule preventive maintenance
Plan a preventive intervention around 12 months of operation to prevent breakdowns and extend life.
- 4Verify operating parameters
Keep the pump within its recommended design parameters — running outside them causes inefficiency and damage.
- 5Observe technical data and warnings
Follow the technical data for installation, operation and maintenance, and heed the warnings in the documentation.
- 6Ensure shaft-seal lubrication
Confirm flush water is connected and flowing to the shaft seal to prevent dry running and seal failure.
- 7Rinse after cleaning
Rinse thoroughly with clean water after any cleaning agent to stop residues degrading components.
- 8Re-check for new applications
If capacity, pressure or the pumped liquid changes, re-check suitability via the configurator or Alfa Laval / DFT.
- 9Stock service kits
Keep OEM service kits on hand to cut downtime when a component needs replacement.
- 10Use the maintenance videos
Alfa Laval 360° service videos guide simple maintenance tasks and correct reassembly.
