GENERAL MAINTENANCE and PERIODIC INSPECTION
!
The Preventive Maintenance section must be
adhered to in order to keep the applicable ATEX
classification of the equipment. Failure to follow
these procedures will void the ATEX classification
for the equipment.
Operating conditions vary so widely that to recommend one
schedule of preventive maintenance for all centrifugal
pumps is not possible. Yet, some sort of regular inspection
must be planned and followed. We suggest a permanent
record be kept of the periodic inspections and maintenance
performed on your pump. This recognition of maintenance
procedure will keep your pump in good working condition
and prevent costly breakdowns.
One of the best results to follow in the proper maintenance
of your centrifugal pump is to keep a record of actual
operating hours. Then, after a predetermined period of
operation has elapsed, the pump should be given a
thorough inspection. The length of this operating period
will vary with different applications, and can only be
determined from experience. New equipment, however,
should be examined after a relatively short period of
operation. The next inspection period can be lengthened
somewhat. This system can be followed until a maximum
period of operation is reached which should be considered
the operating schedule between inspections.
INSPECTION INTERVALS
!
Inspection intervals should be shortened
appropriately if the pumpage is abrasive and/or
corrosive, or if the environment is classified as
potentially explosive.
MAINTENANCE TIMETABLE
EVERY MONTH
Check bearing temperature with a thermometer, not by hand.
If bearings are running hot (over 180° F), it may be the result
of too much or too little lubricant. If changing the lubricant
and/or adjusting to proper level does not correct the condition,
disassemble and inspect the bearings.
EVERY 3 MONTHS
Check the oil on oil lubricated units. Check grease lubricated
bearings for saponification. This condition is usually caused
by the infiltration of water or other fluid and can be noticed
immediately upon inspection, since it gives the grease a
whitish color. Wash out the bearings with a clean industrial
solvent and replace the grease with the proper type as
recommended.
