AMT 5585-010-98 Impeller Xss

The AMT 5585-010-98 is an Impeller Xss for an AMT Pump. IMPELLER AND VOLUTE REPLACEMENT : Impeller and volute are subject to wear only by abrasive sand or sediment laden liquids. If badly worn, all these parts can be replaced and the pump thus restored to full efficiency. NOTE: When the clearance between the impeller and the volute exceeds 1/16 Inch at the face of the impeller or 1/8 Inch on the outside diameter of the impeller, it may be necessary to take corrective action. The increased clearance can cause lengthened priming times and reduce pumping capacity. If both the priming and capacity of your unit are satisfactory for your application, it is recommended that no corrective maintenance be performed regardless of what clearances on your unit may have developed, since the increased clearances in themselves are not generally harmful to your pump. Normally, new pump clearances can be restored by simply shimming behind the impeller. If the impeller is badly worn, it is recommended that the impeller be replaced. This is usually all that is required since only on unusually abrasive services does the cast iron volute show deterioration. Occasionally a stone or hard object might get caught in the impeller and cause damage to the volute/cutwater. In these cases, follow the instructions below for replacement.
