Cavitation and net positive suction head (NPSH) are two of the most vexing problems encountered when selecting and applying centrifugal pumps. We will focus on NPSH issues in commercial HVAC applications, but the principles involved apply to applications in all market sectors. This webinar will take the mystery out of the topic. In plain, simple language - and with examples taken from both open and closed loop piping systems - the whole issue of NPSHa versus NPSHr will be clarified and reduced to a few basic principles and equations.
