Minimum Flow Line for Centrifugal pump
Minimum Flow Line for Centrifugal pump
(OP)
For batch operation, Is it required to have minimum flow line for centrifugal pump? The pump is used intermitently to transfer the material.

If you'd tell us about the application and the flow rate(s) required you may get some more specific guidance.
Good luck,

An understanding of what you are looking to do - flows, pressures, pump size and type etc will be a great start to advise you further.

RE: Minimum Flow Line for Centrifugal pump
The recirculation line is primarily to combat intermittent or variable load from the hydraulic system more often than not from a branched / networked reticulation system: since a reticulation system may feed multiple consumers at different parts of the plant, it is difficult to reconcile the myriad system curves possible with combinations of open and closed consumers. Thus the recirculation line may be nominated to attenuate flow through the pump to derive an optimum head and energy profile. I agree with above that a VSD may be used but this is nevertheless limited to the minimum running speed (and hence draft cooling) of the motor.
Another possible way to reconcile your supply and demand, depending on what it fact your process involves, is the use of header tank which is slow filled and quickly discharged.
