Centrifugal Pump Minute

Friday, July 27th, 2018 von admin

Griswold has developed an educational video blog called the “Centrifugal Pump Minute.”

The first video is about Determining available system NPSHA. James Farley, Griswold Product Manager, reviews how to determine available system NPSHA for a pump that is installed and operational. Using the calculation needed to determine NPSHA, James presents example tests that will establish system performance and possible pump cavitation.
