In order to run a pump smoothly, it is necessary to regularly maintain it, so that it can work efficiently. Usually there is a tendency as the pump runs smoothly, people often overlook even the common maintenance activities and rationalize that it is just not worth spending time in regularly inspecting and replacing the parts. However, nothing can be further from the truth. Hard fact is that in most of the facilities, several pumps perform a number of functions, which are integral to any successful operation of a big plant. In case a pump malfunctions, then it can be the only cause of any shut down of the entire plant.
All sanitary Valves are cogs in all the wheels, which will keep the entire facility functioning efficiently, irrespective of whether they are utilized for any manufacturing processes, water treatment or HVAC. For keeping pumps running properly, always any regular maintenance schedule must be followed and implemented.
- Determine maintenance frequency
Consult the guidelines of original pump manufacturer. Decide the timing in order to schedule the maintenance. Whether the lines or pumps need to be stopped? Select any time when any system is down to take the opportunity or use your common sense to decide about time and frequency.
- Observation is key
Try to know the system and note down the points to be observed in your pump when it is in running condition. Take a note about any leaks, vibrations, any unusual sounds and unusual odors.
- Safety first
Ensure that machines are first shut down properly before performing any maintenance or any systems check. For electrical system proper isolation is very important and also for hydraulic systems too.
- Mechanical inspection
- Check all the mounting points are perfectly secured
- Inspect all the mechanical packing and seal
- Inspect the flanges of pump for leaks
- Do inspection of couplings
- Inspect and also clean filters
Lubricate the pump and motor bearing as per manufacturer’s guidelines. Avoid over lubricating. More bearing damage may occur due to over greasing. In case the bearing has any vent cap, then remove the cap to run your pump for at least 30 minutes prior to reinstalling cap.
- Electrical/motor inspection
- Make sure that all the terminations are tight
- Do inspection of motor windings and vents for any dust/dirt build-up. Clean them as per guidelines of manufacturer.
- Inspect starter/contractor for overheating, arcing etc.
- Use any megohmmeter to check insulation
- Replace damaged hoses and seals
If any seals, hoses, or O-rings may show damage or wear, replace it immediately.
