7. MPELLER SHAFT BEARINGS The MODEL 344A pump is available with three options for lubricating the shaft bearings They are 1 Regreasable standard 2 Oil Lubrication 3 Sealed Bearings Permanent Lubrication Regreasable bearings will require periodic lubrication and can be accomplished by using the zerk or lubrication fittings in the cartridge cap and power frame Lubricate the bearings at regu lar intervals using a grease of high quality Polyurea base CIP AURORA MODELS 341A 342A 344A grease is recommended as lubricants for pumps operating in both wet and dry locations Mixing of different brands of grease should be avoided due to possible chemical reactions between the brands which could damage the bearings Accordingly avoid grease of vegetable or animal base which can develop acids as well as grease containing rosin graphite talc and other impurities Under no circumstances should used grease be reused Over lubrication should be avoided as it may result in overheat ing and possible bearing failure Under normal application ade quate lubrication is assured if the amount of grease is main tained at 1 3 to 1 2 the capacity of the bearing and adjacent space surrounding it In dry locations each bearing will need lubrication at least every 600 hours of running time or every 6 to 12 months whichever is more frequent In wet locations the bearings should be lubricated at least after every 300 hours of running time or
