Maintenance Tips
-
Inspect regularly: Check the pump shaft, seal faces, and O-rings for wear or scoring to prevent leakage and extend seal life.
-
Keep components clean: Remove debris, mineral buildup, and old lubricant before installation to ensure a proper seal seat.
-
Lubricate properly: Apply a compatible lubricant to O-rings and elastomers to reduce friction during assembly.
-
Maintain proper alignment: Ensure the pump shaft is straight and correctly aligned—misalignment is a leading cause of premature seal failure.
-
Monitor operating conditions: Avoid dry running, overheating, or pressure spikes, which can quickly damage the seal.
-
Replace at first signs of wear: Early replacement prevents larger pump failures and maintains optimal system performance.
