Introduction |
| If your Alphacool Eispumpe VPP755 V.1 or V.2 makes a grinding sound during operation, stops and starts randomly or dosen't seem to flow liquid, use this guide to replace the impeller thrust washers. | | The thrust washers provide a low friction surface for the impeller to spin against during operation. Damaged or defective thrust washers can cause the pump to omit a loud grinding noise and negatively effectaffect it’s performance. | | | Step 6 requires you to carefully remove the keeper washer and is the most difficult task for this guide as the keeper can break if removed too aggressively. | | | Before beginning, make sure the pump is disconnected from any power source. |
