How to Interpret Pump Performance Curves

Pump performance curves provide important information for R&D, design engineers, and product developers in selecting the right pump for a given application. Therefore, interpreting pump curves correctly is crucial. This piece reviews the creation and use of diaphragm pump performance curves to determine flow at given vacuum or pressure conditions. Included are: a lesser-known trick to interpolate pump performance when there are flow restrictions on both the inlet and outlet sides of the pump; and a link to a companion video.
