A Cure For Pump Cavitation

 

Cavitation means that cavities or bubbles are forming in the liquid that is being pumped. These cavities form on the low pressure or suction side of the pump.

Most pump piping systems have an elbow within ten pipe diameters of the pump’s suction inlet. The elbow causes a flow turbulence which results in pump cavitation.

 

Pump cavitation sounds as if stones are going through the pump. 

Pump cavitation will results in increased operating costs by causing:

Text Box: •	excessive noise 
•	vibration 
•	poor pump performance 
•	undue wear and tear on the pumps impeller 
•	dangerous leaks 
•	unexpected down times
•	reduced flow and head

                                        The CRV®

 

 

 

 

 

While the CRV® itself has no moving parts, it imparts a rotational flow to the liquid to exactly cancel the rotational effect of the elbow so that the fluid exits the elbow with no turbulence.
