The importance of running clearances in centrifugal pumps

The Importance Of Running Clearances In Centrifugal Pumps

All centrifugal pumps must have clearance between the stationary pump casing and the rotating element. In single stage pumps this clearance is limited to the clearance between the impeller surfaces and the casing, and the clearance between the seal cavity or stuffing-box throat bushing and the shaft.
