At the Pumping Solutions Training Center, Chicago, IL, March 23-24, 2004
Feedback from the attendees:
"Nice selection of pumps in class, and cutaways are a good way of showing the design details"
" Dr. Nelik is very knowledgeable of his practice and - entertaining as well, with a sense of humor. He is an excellent "hands-on-and-theory" type of an instructor"
"A good refresher course on pumps"
"It was interesting to have a "Pre-Test" at the beginning of the class. I changed 50% of my "Pre-Test" answers, after the class, of the same "Post-Class" Questionnaire test"
"I did not know much about the hydraulics, and formulas. I feel much better about that after the class"
"Class would be very helpful to many of our mechanics and maintenance crew"
Some of the class "mementos"...
Live running of a Progressing Cavity pump, equipped with a power monitor, to detect dry running, as well as over-pressure.
Motor power monitor - a good way to detect pump dry running, with set point easily fine-tuned by the pump user.
"Do I feel this blower vibrating? Do I? Do I not? Well, I guess the sound enclosure is working pretty good!"
And this is how a rotary blower works... In fact, lobe pumps operate on a similar principle, and look similar.
Gear pumps, multiple screw pumps, progressing cavity pumps - cutaways and actual working models, were part of the learning.
O, no! - Why didn't you tell me that this non-metallic mag-drive pump can handle touch chemicals before?! I have just an application for it at my mill!
Metering pumps and systems - a self-contained unit, ready to go, including a calibration column, for better accuracy.
Regenerative Turbine pumps - an interesting design: extremely low NPSH capability, and - handling significant volumes of gas, such as encountered in multi-phase pumping.

No matter what technology does - a Hammer is still a
Hammer!
Progressing Cavity stator "thin-equal-wall"
design - for higher pressure, and longer life.
