Course Description:
"CENTRIFUGAL AND POSITIVE DISPLACEMENT PUMPS: Theory, Applications and Hands-On" by
Dr. Lev Nelik, P.E., APICS Cell 770-310-0866
You receive 1.8 Continuing Education Units (CEU) and qualify for 15 Professional Development Hours needed to fulfill Professional Engineers’ continuing education requirements in many states.
Note: Open School class in Atlanta starts 8 am thru 4 pm, both days. For on-site classes, the starting and ending times are determined as best fits the hosting company (typically 7:00 am thru 3:30 pm).
Level I (BASICS) Course Description and Audience (for Advanced, Level II, scroll further below) This 2-day action-oriented course is prepared for maintenance personnel, engineers, equipment reliability leaders, plant operators, purchasing and facility management who are involved with pumps, and want to get a better understanding of pump designs, application-related differences between the pump types, as well as obtain a practical and unique hands-on reassembly experience to supplement the theory. The course provides an opportunity to review, refresh and enhance the attendants' pump knowledge, and to learn the latest pump technologies to help solve their specific problems. It also provides an opportunity to interact, learn from the instructor and from each other, and to implement the troubleshooting techniques at the facilities immediately following the training.
The course will introduce participants to the different types of pumps and their associated terminology. Centrifugal and Positive-Displacement pumps, packing, mechanical seals and sealing systems, bearings and couplings will all be discussed. The application of the different types of pumps will be discussed along with their suitability for different operational duties. Pump operation, troubleshooting and maintenance will be dealt with in depth. Pump to motor alignment, effect of piping loads and energy savings through efficiency improvement and identification of the regime of operation to avoid problems present practical and immediate opportunities for implementation at the plant level. Actual testing of live pumps is conducted by the attendees in class, and the obtained performance curves are plotted.
The course will also benefit anyone who wishes to update themselves on pump technology, judge the suitability of different types of pumps for their needs, and learn how to operate and maintain them for the benefit of their organizations. A hands-on part of the course is a unique opportunity to "get hands dirty" and to see, firsthand, the internals of the equipment, which they otherwise might have only seen on drawings, specs and books. Conversely, plant mechanics and maintenance people will get an opportunity to put the theory, the "why’s and what’s", behind their practical knowledge. Every attendee thus will walk away with something new, specific and helpful for their personal development as well as immediate benefits to their companies. Objectives At the end of this course participants will:
Prerequisites The attendees should have some basic knowledge of machinery, such as pumps, or mixers, motors, turbines, etc. Dress casual, prepare to work with tools, although no heavy lifting. Bring a calculator.
Special Features In additional to theory and hands-on reassembly work, the participants will be testing pumps, obtain and plot H-Q curves using a single centrifugal seal-less mag-drive pump, and then two pumps operating in parallel.
Assessment Measures A self-check List-of-Learning is provided. By answering a 1-page questioner at the beginning of the course and comparing with same at the end of the course, each participant will be able to do a self-evaluation summary of his or her accomplishments during the course.
Key Benefits The knowledge gained in this course will:
Training Methodology The course will be conducted along workshop principles with formal lectures, case studies and interactive hands-on work. Relevant case studies will be provided to illustrate the application of each tool in an operations environment. Each learning point will be opportunities for discussion and sharing experiences.
Organizational Impact On completion of this course the attendee will be able to critically analyze the methodologies employed within the Organization and instigate improvements where required.
Personal Impact Technical knowledge is key to effective control and peer respect within any maintenance organization; when this is achieved personal satisfaction follows. This course will give the attendee the required level of technical knowledge and skill to achieve that personal satisfaction and professional growth.

Changes, Cancellations, Refund Our facilities' arrangements and pre-planning, events reservations, transportations of course materials, printing of books, and similar logistics require us to make long term advanced planning of training seminars. This make it difficult to allow refunds. In the event you can not attend the training, our policy allows the following options: a. You can send a qualified substitute(s) b. If no substitute is available, for special circumstances (death in a family, inclement weather, work strikes, or an agreed upon special arrangements), we can allow one free switch-over to any training within the next (12) months c. You can apply the registration fee toward the training to be scheduled for a group, on-site, at your facility, within the next (24) months
