monobloc suction side of a centrifugal pump

What could happen if air pockets present at suction side

Answer Wiki. Air pockets in the suction side means a cavitating pump. Cavitation in general terms is used to describe the behavior of voids or bubbles in liquid. Any time a flowing liquid falls below its vapor pressure, vapor bubbles can form. If the flowing liquid is then subjected to pressures above the vapor pressure

Check Valve In Centrifugal Pump Industrial Professionals

Jan 13, 20120183;32;The check valve is present to prevent any backflow through the pump. When the pump is pumping, it delivers liquid from low pressure (suction) to high pressure (discharge side). If the pump trips due to any reason, there is a driving force for the liquid to flow from the discharge piping (high pressure area) into the suction piping (low pressure area) through the pump casing, which will 1.

PUMPS DON'T SUCK And Other Centrifugal Pump Basics

Centrifugal pumps move fluid by using centrifugal force to generate velocity of the liquid. Fluid enters the pump through the suction nozzle, into the eye of the impeller. The impeller vanes catch the fluid and rotate it, both tangentially and radially until it exits the pump on the discharge side.
