Commissioning, Startup, Operation, and Shutdown (Continued)Impeller-clearance settingImportance of a proper impeller clearanceImpeller clearance methodsA proper impeller clearance ensures that the pump runs at high performance.WARNING:• The impeller clearance setting procedure must be followed. Improperly setting the clearance or notfollowing any of the proper procedures can result in sparks, unexpected heat generation, andequipment damage.• If you use a cartridge mechanical seal, you must install the centering clips and loosen the set screwsbefore you set the impeller clearance. Failure to do so could result in sparks, heat generation, andmechanical seal damage.You can set the impeller clearance with either of these methods:• Dial indicator method• Feeler gauge methodSet the impeller clearance - dial indicator method (all except CV 3196)WARNING:Always disconnect and lock out power to the driver before you perform any installation or maintenancetasks. Failure to disconnect and lock out driver power will result in serious physical injury.1. Remove the coupling guard.2. Set the indicator so that the button contacts either the shaft end or the face of the coupling.370C134A228423370D3. Loosen the jam nuts (423) on the jack bolts (370D) , and then back the bolts out about two turns.4. Tighten the locking bolts evenly (370C), bringing the bearing housing (134A) towards the frame (228)until the impeller contacts the casing.5. Turn the shaft to ensure that there is contact between the impeller and the casing.6. Set the indicator to zero and loosen the locking bolt (370C) about one turn.7. Thread in the jack bolts (370D) until the jack bolts evenly contact the bearing frame.8. Tighten the jack bolts evenly about one flat at a time, moving the bearing housing (134A) away fromthe bearing frame until the indicator shows the correct clearance.50 Model 3796 i-FRAME Installation, Operation, and Maintenance Manual
Refer to the impeller clearance table to determine the correct clearance.9. Tighten the bolts evenly in this order:a) Tighten the locking bolts (370C).b) Tighten the jack bolts (370D).Make sure to keep the indicator reading at the proper setting.10. Make sure the shaft turns freely.Set the impeller clearance - feeler gauge method (all except CV 3196)WARNING:Commissioning, Startup, Operation, and Shutdown (Continued)Always disconnect and lock out power to the driver before you perform any installation or maintenancetasks. Failure to disconnect and lock out driver power will result in serious physical injury.1. Lock out the driver power and remove the coupling guard.2. Loosen the jam nuts (423B) on the jack bolts (371A), and then back the bolts out about two turns.370C.015371A423B134A2283. Evenly tighten the locking bolts (370C), bringing the bearing housing (134A) towards the frame (228)until the impeller contacts the casing.4. Turn the shaft to ensure that there is contact between the impeller and the casing.5. Use a feeler gauge to set the gap between the three locking bolts (370C) and the bearing housing(134A) to the correct impeller clearance.Refer to the impeller clearance table to determine the correct clearance.6. Use the three jack bolts (370D) to evenly loosen the bearing housing (134A) until it contacts thelocking bolts (370C).7. Evenly tighten the jam nuts (423B).8. Set the indicator to zero and turn back the locking bolt (370C) one turn.9. Thread the adjuster bolts (371A) in until they evenly contact the bearing frame.10. Tighten the adjuster bolts evenly (about one flat at a time) and back the bearing housing (134A) awayfrom the bearing frame until the indicator shows the proper clearance per the Cold temperature axialclearance (open and closed impeller) table.11. Evenly tighten the locking bolts (370C) and then the adjuster bolts (371A) while keeping the indicatorreading at the proper setting.12. Make sure the shaft turns freely.Couple the pump and driverWARNING:Always disconnect and lock out power to the driver before you perform any installation or maintenancetasks. Failure to disconnect and lock out driver power will result in serious physical injury.Model 3796 i-FRAME Installation, Operation, and Maintenance Manual 51
