CRV flex and Pump Applications Download White Paper>>

When poorly developed flow enters the pump impeller, it strikes the vanes and is unable to follow the impeller passage. The liquid then separates from the vanes causing mechanical problems due to cavitation* and vibration, and performance problems due to turbulence and poor filling of the impeller...

CRV Flex Operating Principles Download White Paper>>

When the CRV Rotation-Vane is placed immediately\upstream of an elbow, it rotates the flow entering the elbow. As a consequence, the fluid negotiates the turn with all the streamlines traveling approximately the same distance (equal flow path lengths) from entrance to exit, as illustrated in Figure 1(a)-right, and...

Metraflex CRV in a Reducing Elbow Simulation Download White Paper>>

The Metraflex six-bladed CRV flow conditioner was analyzed to determine its effect in a 4" to 3" reducing elbow with a water velocity of 5 feet per second. The simulation was conducted using CFdesign version 9.0 from Blue Ridge Numerics, Inc. Download White Paper>>
