Easy Way to Troubleshoot Pump Problems
By: Thomas Yoon
In any problem analysis, we have to specify the problem, check
whether there is any deviation from the normal condition,
identify the possible causes, evaluate the possible causes and
then confirm the true cause.
Pumps or other machinery will give tell tale signs when they are
not working properly. An observant pump user will be able to
avoid major breakdowns or damage if the problem is corrected early.
In order to solve any pump problem, we need to notice the
symptoms carefully so as to determine the most likely causes.
Instruments like pressure gauges are very helpful and should be
installed in the pumping system.
Very often we do have to rely on our 5 senses to pinpoint the
exact symptom. Normally, pump problems can be classified into
Suction Related, System Related, or Mechanical Related. It can
also be a combination of these.
Most of the system related problems occur because of design flaw.
For example, the designer may have chosen the wrong pump whose
characteristic does not match the system requirement. Suction
related problems are usually caused by air lock that are due to a
variety of reasons...
The effects of mechanical related problems could manifest
themselves as suction related problems - air leaks in the system,
worn out impellers, and mouth rings - but the most common symptom
is the presence of vibration and abnormal noise in the equipment.
DiagnoPump, pump troubleshooter has been created for pump users and
sellers to help them find the solution quickly. Arranged so that
the easiest (and often overlooked) causes are examined first, it
could be a very useful tool.
If you are a beginner, you can start the troubleshooting from the
very first steps. More experienced users may want to start from
the later stages in the symptom list. The symptoms have been
identified to make it easy to zero in on the correct ones. The
symptoms have been arranged as:
- No Flow, No Pressure - No water delivered at all
- Low Flow and Low Pressure - Pump does not deliver sufficient
water or Pump does not deliver water after some time or
Insufficient pressure developed
- Short Lifespan of Shaft Seal or Packing - Shaft seal or Gland
Packing does not last long
- Short Lifespan of Bearings, Noisy Operation - Bearings do not
last long or Vibration and noisy operation or Overheating of parts
or Seizure of bearings
- Pump Trips - Pump stops by itself or Excessive power consumption
With this easy pump troubleshooter, anyone could easily pinpoint the causes
in a very short time. The pump troubleshooter can be downloaded for
The usefulness does not end there - any pump distributor or seller
can also make use of it to sell their own product! They are able to
insert their own names and Companies into the FREE software and
distribute it to anyone they wish as goodwill.
