Impeller Clearance Settings Flowserve recommends the following impeller settings based on the pump sizes. If the Pump Size Is: Size 6 thru size 12 Size 14 and above Settingfor Enclosed Impellers 3~4 mm (0.13~0.15 in) 6~7 mm (0.25~0.27 in) Setting for Semi-Open Impellers 0.25 mm to 0.38 mm (0.010 in to 0.015 in) 0.63 mm to 0.76 mm (0.025 in to 0.030 in)

Note: Shafts elongate due to the hydraulic thrust of the pump and the impellers must be compensated for this elongation. Shaft elongation varies for each model depending upon the size, shaft length, shaft diameter,impeller weight, number of stages. Please see the documentation supplied along with the pump for exact impeller setting value matched for the specific pump that you have purchased
