7 Simple Maintenance Steps for the Pump

When things are going well, it’s easy to overlook routine maintenance and reasonably believe that it’s not worth taking the time to check and replace parts on a regular basis. But the reality is that most plants have multiple pumps to perform the functions that are essential to the successful operation of a plant. If one pump fails, it may cause the entire plant to stop operating.



The pump is like a gear in a wheel, whether it is used in manufacturing processes, HVAC or water treatment, it can make the plant run efficiently. To ensure proper pump operation, regular maintenance schedules should be followed and followed.

Determine maintenance frequency

Review the original manufacturer’s guidelines and consider scheduling repairs. Does the production line or pump need to be shut down? Choose a time when the system is shut down and use common sense to develop maintenance schedules and frequencies.

Observation is the key

Understand the system and watch it as a good candidate while the pump is still running. Record leaks, unusual sounds, vibrations and unusual odors.

Safety first
Make sure the machine is properly shut down before performing maintenance and/or system checks. Proper isolation is important for both electrical and hydraulic systems. Mechanical inspection
1. Check if the installation point is safe;
2. Check mechanical seals and packing;
3. Check the pump flange for leaks;
4. Check the joints;
5. Check and clean the filter.
Lubricate the motor and pump bearings according to the manufacturer’s guidelines. Remember not to over-lubricate. Many bearing damages are caused by excessive lubrication rather than insufficient lubrication. If the bearing has a venting cap, remove the cap and run the pump for 30 minutes before reinstalling the cap to drain excess grease out of the bearing.
Electrical ╱ motor inspection
1. Check if all terminals are tight;
2. Check the motor vents and windings for dust/dirt accumulation and clean according to the manufacturer’s instructions;
3. Check the starter/electrical equipment for arcing, overheating, etc.
4. Use a megohmmeter on the winding to check for insulation faults.
Replace damaged seals and hoses
If hoses, seals or O-rings are worn or damaged, they should be replaced immediately. Use temporary rubber assembly lubricants to ensure a tight fit and prevent leakage or slippage.There are a lot of lubricants on the market, including better old-fashioned soap and water. Why do you need a specially formulated rubber lubricant? It has been proven that many pump manufacturers do not recommend the use of petroleum, petroleum jelly or other petroleum or silicon based products for the lubrication of elastomeric seals. Welcome to the pump circle. The use of these products will result in seal failure due to expansion of the elastomer. Rubber Lubricating Oil is a temporary lubricating oil that, once dried, no longer acts as a lubricant and keeps the parts in place. In addition, these lubricants do not react in the presence of water and do not dry the rubber parts.
