MS717 · Cavitation in Pumps

Cavitation in pumps experiment — visual and vibration study of cavitation in a centrifugal pump

Experiments

Experimentally inducing cavitation in a centrifugal pump by throttling the intake
Visual observation of cavitation bubbles through the transparent pump housing
Stroboscopic analysis of cavitation (stroboscope sold separately)
Identification of cavitation in the vibration spectrum
Investigation of the normal operational vibrations of a centrifugal pump
Pump driven directly (via coupling on MS700) or via the MS714 belt drive
Interpretation of frequency spectra and use of the Sangari vibration analysis software

Description

Cavitation is one of the dominant sources of vibration in centrifugal pumps. The MS717 experiment makes the phenomenon visible and measurable on the laboratory bench: a single-stage centrifugal pump with a transparent housing draws water from a 20 L tank, and valves plus manometers on the intake and delivery lines let the student set any operating point — including those at which cavitation bubbles appear inside the impeller.
