HIGH QUALITY WATER PUMPS
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.
DETERMINE MAINTENANCE FREQUENCY
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.
IFC Tubes - OBSERVATION IS KEY
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 odors.
SAFETY FIRST
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.
MECHANICAL INSPECTION
Check that mounting points are secure:
- - Inspect the mechanical seal and packing
- - Inspect the pump flanges for leaks
- - Inspect the couplings
- - Inspect and clean filters
LUBRICATION
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 and water pump.
ELECTRICAL/MOTOR INSPECTION
- - Check that all terminations are tight
- - Inspect motor vents and windings for dust/dirt build-up and clean according to manufacturer’s guidelines
- - Inspect starter/contractor for arcing, overheating, etc.
- - Use a megohmmeter on the windings to check for insulation failure
REPLACE DAMAGED SEALS AND HOSES
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. Relis Systems offers a unique line of temporary rubber lubricants. Our P-80® lubricants are available in six water-based formulas that offer superior lubrication and are compatible with a variety of surfaces. P-80 lubricants are environmentally friendly, most are biodegradable.There are numerous lubricants out there, including good old soap and water, so why do you need specially formulated rubber lubricants?
The facts speak for themselves:
Many pump manufacturers advise against the use of oil, petroleum jelly or other petroleum or silicon based products for elastomer seal lubrication. Using such products could cause seal failure due to swelling of the elastomer. P-80 rubber lubricants are temporary, once dry the lubrication ceases and parts stay in place. Additionally, these lubricants will not reactivate in the presence of water and they will not dry out rubber parts. Keep your facilities running smoothly. Try P-80® temporary rubber assembly lubricants for your pump maintenance needs. Visit www.relis.co.za to speak with a specialist and request a sample for testing.
