Viscosity, Pump, Centrifugal, Cavitation, Static, Impeller, Suction, Dynamic, Displacement
Pumps are a critical component of beer production to control the movements of fluids (gases, and liquids) throughout the process. This lecture discusses the fundamentals of both centrifugal and positive displacement pumps. In order to select the right pump for a particular application, one needs to understand the basics such as suction head, vapor pressure, cavitation, and viscosity, as well as pump curves and pressure losses associated with piping systems. All those concepts are covered in details, and several scenarios will be presented, guiding you through successful pump troubleshooting.

Gary Grande performed in a number of roles in a variety of industrial environments over a forty year period. The most recent of these was Miller Brewing Company where he held numerous positions in the brewery production and maintenance functions, and also directed several engineering projects and upgrades. He also served as an internal packaging and process consultant for breweries within the Miller system. He directs the consultancy and research functions at the Siebel Institute, as well as managing the Process Technology module of the WBA International Course in Brewing Technology. He lectures part of that module as well as other Siebel Institute courses. He is also licensed as a Broadcast Engineer by the U.S. Federal Communications Commission.
