Centrifugal Pump Design & Performance
This course is designed to help engineers design, test, and run pumps and systems that are more effective, more economical, and more reliable. Engineers will come to understand the best state-of-the-art design practices and learn the latest theories on performance, cavitation, dynamic forces, and noise. The course will review the latest advances in design tools, and will provide expert and relevant instruction to designers on pump design optimization.
The course begins with an extensive survey of the current technology base for pump design, covering impellers, diffusers, volutes, and other flow elements. The limitations on pump operation and range due to stall and other instabilities are described. Special attention is given to problems and design issues specifically associated with pump flows, namely cavitation, unsteady flow, and vibration. The analysis of stress and vibration in centrifugal pumps will be covered in detail.
NEW! Recent progress has been made in the broad modeling (using a common core model) of impellers, diffusers, return channels, etc., which enhances design capability today. This work is surveyed during the course.
Emphasis is placed on modern methods available to the pump designer for blade layout and design, using flexible geometric techniques associated with hydrodynamic loading calculations and the computational fluid dynamic analysis of pump flows. The advantages and limitations of such analysis are reviewed thoroughly by the instructor.
Participants earn 2.7 Continuing Education Units (CEUs).

Dr. David Japikse
Dr. Japikse received his master's and doctoral degrees at Purdue
University. He founded Concepts ETI in 1980 and guided the company
as president until 2000 when he led the acquisition of NREC's
consulting and engineering software business. He currently serves
as Concepts NREC's chairman of the board. He has been responsible
for many activities in centrifugal pump design, consulting, and
research, and has developed a number of innovative design techniques.
Dr. Japikse has also published extensively and teaches regularly
to engineers. He has received many awards including the James
Harry Potter Gold Medal from ASME for "…innovative, pioneering
contributions in the field of thermodynamics as applied to turbomachinery
design." He is a Fellow in the ASME and a member of the National
Academy of Engineering.
Dr. Karl Wygant
Dr. Wygant received his master's and doctoral degrees at the University of Virginia. Prior to joining Concepts ETI in 1998, Dr. Wygant worked as an analytical engineer for Dresser-Rand of Wellsville, New York, and an independent rotor dynamics consultant, before being contracted to serve in the same capacity by Duke Engineering Services. Dr. Wygant is extremely accomplished in several engineering disciplines with a specific focus on rotordynamics analysis and bearing design. He is currently Director of Mechanical Engineering at Concepts NREC.
