Description: The second most common and most sold piece of mechanical rotating equipment is the centrifugal pump (ANSI, split case, VFD). Here is a course that deals with the 15 most common pump problems and teaches the attendee how to spot the problem and what is needed to correct things. The course covers simple tests using the eyes, ears, and sense of touch as well as the use of a simple hand-held vibration meter to determine internal conditions within the pump and the bearings. Problems isolation such as, “Is it the pump or the motor?” and hydraulic related issues such as, “Why doesn’t the pump meet capacity?” and “Why doesn’t the pump produce enough pressure?” are discussed. The attendee walks out of the course with a much better knowledge about how to handle field problems and learns to make good decisions to get the plant back in operation as soon as possible by being “right on” in figuring out what’s wrong and fixing it.

PUMPS AND MOTORS — A short history
What’s the difference between a positive displacement and centrifugal pump?
John Appold and the curved vane centrifugal pump

The Bernoulli principle and centrifugal pumping
Parts of a pump and what they do
Pump packing
Pump seals
How to calculate pump head
Head vs. Flow curves
Simple pump and system curves and how to use them
Reading a pump nameplate

Hydraulic problems –
– Pump not meeting head (pressure) requirements (use of pressure gauges)
– Pump not meeting capacity requirements
– Suction problems (use of pressure gauges)
– Air entrainment and cavitation (determining which is which)
– Pump will not prime
– Pump is noisy and shakes
Mechanical problems –
– Unbalance
– Looseness
– Misalignment
– Bent Shaft
– Bad bearings – listening for the “beach” noise
– Loose or fouled impeller – improper direction of rotation
– Excessive packing leak
– Mechanical seal failure
– Improper lubrication – learning how to properly lubricate a pump

More than 50% of the course will be “hands-on” and each student will receive work books and supervised instruction as well as individual one-on-one assistance to make sure they can accomplish the tasks assigned. It is expected that an attendee will leave the class with the basic knowledge and skill to handle any pump troubleshooting situation. Class books can be used on the job site in the future to assist with troubleshooting steps and refresh the tasks that need to be done.

One day duration (8 hours) and up to 15 students may attend. Call or email for dates of next scheduled session. Phone: (302) 690.0871 Email:
