AMT 3590-010-95 Impeller - Cast Iron

The AMT 3590-010-95 is a 359 Impeller Gf and 496P XCI, Cast Iron for an AMT Pump. IMPELLER AND WEARPLATE REPLACEMENT
Impeller , volute/wearplate and rear wearplate are subject to wear only by abrasive sand or sediment laden liquids. If badly worn, all these parts can be replaced easily and the pump thus restored to full efficiency. NOTE: When the clearance between the impeller and the volute/wearplate exceeds 1/16 at the face of the impeller or 1/8 on the outside diameter of the impeller, it may be necessary to take corrective action. The increased clearance can cause lengthened priming and decreased capacity to your unit. If performance is satisfactory for your application, it is recommended that no corrective maintenance be performed regardless of what clearances on your unit may have developed. This is because 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 abrasive surfaces does the cast iron wearplate 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 : 1. Disassemble pump for access as described in Mechanical Seal Replacement, steps 1 and 2. 2. Replace parts as necessary. NOTE: When replacing volute/wearplate, attach flapper valve assembly to the new volute with fastener . 3. To replace rear wearplate , remove fasteners after impeller has been removed. NOTE: Before Installing new parts, clean all mating surfaces thoroughly.
