<strong>Maintenance</strong> (Continued)Packed stuffing-box maintenanceAccepted leakage rateAdjustment of gl<strong>and</strong>Tightening of packingWARNING:• Packed stuffing boxes are not allowed in an ATEX-classified environment.• Never attempt to replace the packing until the driver is properly locked out <strong>and</strong> the coupling spacer isremoved.It is not necessary to shut down or disassemble the pump to inspect the packing operation. During normaloperation, the packing should leak approximately one drop per minute.Adjust the gl<strong>and</strong> if the leakage rate is greater than or less than the specified rate.Evenly adjust each of the two gl<strong>and</strong> bolts with a one-quarter (1/4) turn until the desired leakage rate isobtained. Tighten the bolts to decrease the rate. Loosen the bolts to increase the rate.NOTICE: Never over-tighten packing to the point where less than one drop per minute is observed.Over-tightening can cause excessive wear <strong>and</strong> power consumption during operation.If you cannot tighten the packing to obtain less than the specified leakage rate, then replace the packing.DisassemblyDisassembly precautionsWARNING:• Make sure that the pump is isolated from the system <strong>and</strong> that pressure is relieved before youdisassemble the pump, remove plugs, open vent or drain valves, or disconnect the piping.• Always disconnect <strong>and</strong> lock out power to the driver before you perform any installation ormaintenance tasks. Failure to disconnect <strong>and</strong> lock out driver power will result in serious physicalinjury.• Crush hazard. The unit <strong>and</strong> the components can be heavy. Use proper lifting methods <strong>and</strong> wear steeltoedshoes at all times.• The pump can h<strong>and</strong>le hazardous <strong>and</strong> toxic fluids. Identify the contents of the pump <strong>and</strong> observeproper decontamination procedures in order to eliminate the possible exposure to any hazardous ortoxic fluids. Wear the proper personal protective equipment. Potential hazards include, but are notlimited to, high temperature, flammable, acidic, caustic, explosive, <strong>and</strong> other risks. You must h<strong>and</strong>le<strong>and</strong> dispose of pumped fluid in compliance with the applicable environmental regulations.NOTICE:Make sure that all replacement parts are available before you disassemble the pump for overhaul.Tools requiredIn order to disassemble the pump, you need these tools:• Bearing puller• Brass drift punch• Cleaning agents <strong>and</strong> solvents• Dial indicators• Feeler gauges• Hex wrenches• Hydraulic press68 Model 3796 i-FRAME <strong>Installation</strong>, <strong>Operation</strong>, <strong>and</strong> <strong>Maintenance</strong> <strong>Manual</strong>
