This 3-hour audio online course covers key features, operating ranges and problem areas of centrifugal and positive displacement pumps. The discussion on centrifugal pumps covers impeller types, capacity ranges, material selection, and suitable operating conditions. Problem areas are discussed, such as cavitation, low flow, vapor bind, reverse rotation and high flow. The course author, who has over 40 years of experience designing and troubleshooting pumping systems, provides anecdotal advise on recognizing symptoms of pump problems in the field.

Positive displacement pumps are discussed, including reciprocating, gear, diaphragm and progressive cavity pumps. Additionally, considerable attention is paid to hose-type pumps, which are not well known and certainly are not widely covered in traditional pump selection resource guides. Typical applications for positive displacement pumps are covered, as well as problems specific to each type of pump.

The course also discusses pump drivers, including electric motors, turbines, diesel engines and air-operated pumps. Prevention of motor overload and applications for variable speed motors are discussed. Finally, piping suction and discharge piping problems are discussed. Methods are discussed to reduce the potential for entry of vapor into the pump suction. Parallel and series pump configurations are also covered.
