Understanding Net Positive Suction Head

Pumps operate by creating low pressure at the inlet which allows the liquid to be pushed into the pump by atmospheric or head pressure (pressure due to the liquids surface being above the centerline of the pump). Consider placing a pump at the top of the mercury barometer above Even with a perfect vacuum at the pump inlet, atmospheric pressure

Am I experiencing pump cavitation or something else

With the first result, the pump is now operating at a lower flow that requires a lower level of NPSH, and the quieter, smoother operation identifies that Cavitation is being eliminated. If the noise and vibration gets worse, it tells us that the pump is moving into a worsening condition of low flow which demonstrates a problem with Recirculation.

NPSH amp; How it Relates to Slurry Pumps EDDY Pump

Since pumps rely on creating patterns of high and low pressure levels to move materials through the system, low pressure areas can suddenly cause liquids to spontaneously boil. By ensuring the system always provides enough NPSH, pressure levels stay above the cavitation point and vaporization bubbles out of the pump.

What is Pump Cavitation? Crane Engineering

What is pump cavitation? Simply defined, cavitation is the formation of bubbles or cavities in liquid, developed in areas of relatively low pressure around an impeller. The imploding or collapsing of these bubbles trigger intense shockwaves inside the pump, causing significant damage to the impeller and/or the pump housing.
