When things are running smoothly it's easy to overlook common maintenance chores and rationalize that it's not worth the time to regularly inspect and replace parts. But nothing could be farther from the truth. The reality is that most facilities have several pumps performing a variety of functions that are integral to the successful operation of the plant. If a pump malfunctions it can be the cause of an entire plant shut down.
Pumps are the cogs in the wheel that keep your facility functioning efficiently, whether they are used for manufacturing processes, HVAC, or water treatment. To keep pumps running properly, a regular maintenance schedule should be implemented and followed.
Consult the original manufacturer's guidelines. Consider the timing to schedule your maintenance. Will lines or pumps have to be disabled? Select a time when the system is down and use common sense when deciding the time and frequency.
Get to know your system and make a point to observe your pump while it is still running. Make note of leaks, unusual sounds or vibrations and unusual odours.
Make sure machines are properly shut-down before performing your maintenance and/or systems check. Proper isolation is important not only for electrical systems, but for hydraulic systems as well.
Lubricate the motor and pump bearing per manufacturer's guidelines. Be sure not to over lubricate. More bearing damage occurs as a result of over greasing than under greasing. If the bearing has a vent cap, remove the cap and run the pump for 30 minutes before reinstalling cap. This will allow excess grease to work its way out of the bearing.
If any hoses, seals, or O-rings show wear or damage, replace immediately. Using a temporary rubber assembly lubricant will ensure a tight fit and prevent leaks or slips.
