English
What you'll learn
- Learn that most pump problems don’t start in the pump—they begin in the system it’s connected to.
- Learn how to read a pump curve because the pump curve is the pump DNA.
- Learn why the majority of pump system problems are on the Suction Side
- Learn why pump problems are usually associated with Noisy Operation
- Learn why NPSH is so important in a pump system
- Learn how Cavitation occurred and cavitation is a result of insufficient NPSH
- Learn that Cavitation is not the only phenomena that caused bubbles to form but also recirculation and air entrapment
- Learn to identify and differentiate the different between cavitation and other bubble forming problems and what are some possible solutions.

Cavitation And Common Pump Problems
Industrial pump systems are the backbone of many manufacturing and processing operations. By moving liquids, slurries, pumps enable continuous production and efficient workflows. However, like any mechanical equipment, pumps are susceptible to wear, damage, and other issues leading to pump failure or suboptimal performance.
Being aware of the most prevalent pump problems, their underlying causes, and solutions can empower maintenance teams to get ahead of pump failures. With proactive maintenance and attentive troubleshooting, facilities can avoid costly downtime and keep their pump systems running smoothly.
Keeping a handle on common pump failure modes allows issues to be rapidly diagnosed and addressed before causing lengthy outages. Paired with sound maintenance practices, plants can take back control of pump reliability, uptime, and performance.
If you are in the kind of plant where repetitive pump failure is causing ongoing problems like lost production, expensive downtime, environmental difficulties and excessive maintenance costs. You need to know that pump problems have very practical solutions and the repetitive failure can be stopped.
A centrifugal pump is not designed to develop one head at a single capacity. A pump is designed and produced to supply a whole range of head-capacity conditions as identified on it’s performance curve. For all practical purposes, the system controls the pump. To understand how a pump works, we need first to understand the pumping system regarding pump head, Pump Performance Curve and NPSH.
This course will highlight some common pump problems and in particular cavitation. The great majority of pump problems are with the Pump System. The majority of pump system problems are on the Suction Side. Pump problems are usually associated with Noisy Operation. Air entrapment and recirculation also produces noise as in cavitation.
This course will help you learn to identify which is which and come out with some solutions.
Who this course is for:
- All levels of technical staff who are involve in the plant operation , maintenance and installation of pump and its piping system as well as those who are interested to deepen their knowledge about the subject.
