Centrifugal Pump Recycle
Centrifugal Pump Recycle
(OP)
Can someone please explain why a restriction orifice is required at the recycle line of a centrifugal pump? Where is the best position along the line to install it? Does the RO serve the high pressure build-up or the increased flow and velocity purpose. I understand the use of th flow valve on the recycle line and a flowmeter on the pump discharge. Also I understand the use of the ARC valves but not the RO.

It can be installed any where along the recycle line.

If a continuous minimum flow is provided by means of a continuous flow recirculation line with a restriction orifice, the recirculating flow should be added to the rated flow. Hope this help.
