Gland AssemblyCHALLENGESOLUTIONApply Loctite ® 572 Thread Sealant• Loctite ® 572 Thread Sealant fills the air space within the threads• Allows the flushing connector to be removed with normal hand tools when necessaryPrevent corrosionwithin the gland flushing connectorCause:• Whether using a mechanical seal or packing, these components aretypically cooled and lubricated by either a product flush or an externalflush. In either case, the flushing connector is prone to corrosion andseizure. This is especially true for pumps configured with packing. Sincepacking typically requires 40–60 drops per minute for proper coolingand lubrication, there is plenty of available moisture for rust to attack thegland assembly componentsSteps:1. Clean the parts with Loctite ® 7063 Cleaner & Degreaser2. Apply a band of Loctite ® 572 Thread Sealant to male threads starting one to twothreads from the end of the fitting3. Assemble parts snugly. Do not overtightenRESULTS• Prevention of leaks and corrosion• Eliminated seizure• Ensured easy maintenance of flushing connectors30 31
Pump CasingCHALLENGESOLUTIONPrevent the frame adapter,stuffing box and casing fromseizing togetherCause:• When assembling these components, there are areas where theclearance is very tight. These small clearances are areas where rustand corrosion can work in to seize the components together, makingdisassembly very difficultApply Loctite ® 8023 Marine Grade Anti-Seize compoundduring assembly• Loctite ® Anti-Seize compounds have superior water washout resistance,they will stay where they are appliedSteps:1. Clean the parts2. Apply Loctite ® 8023 Marine Grade Anti-Seize to the outside diameter of the stuffing box at the mating point3. Assemble components as usualRESULTS• Sufficient lubrication provided during assembly• Prevention of rust while in service• Efficient disassembly32 33
