Diaphragm pumps are positive displacement pumps, meaning they use contracting and expanding cavities to move fluids. For more information about this category of pumps, visit the Positive Displacement Pump Selection Guide page on IEEE GlobalSpec. Diaphragm pumps work by flexing the diaphragm out of the displacement chamber.

In structural engineering, a diaphragm is a structural element that transmits lateral loads to the vertical resisting elements of a structure (such as shear walls or frames). Diaphragms are typically horizontal, but can be sloped such as in a gable roof on a wood structure or concrete ramp in a parking garage.

The most important factor affecting a diaphragm seal's performance is the integrity of the filled assembly. A filled diaphragm seal and pressure instrument assembly must be free of contamination and air. The presence of contaminants and/or voids in the assembly will produce inaccuracies seen by the pressure instrument.
