Dear all expert

 

As I know in general the centrifugal pump should have minimum flow and I can see in pump datasheet. But some when I look at some pump data sheet, it is not appear. my question is in specific case, can centrifugal pump did not have minimum flow?

 

And

 

In general centrifugal pump will have minimum flow line to recycle to suction pump. But some pump we did not see. my question is Can centrifugal pump did not have minimum flow line?

 

Best regard,

Sapao,

 

Yes, it can..

 

The pumps don't require minimum flow line may be used intermittently or applied in a closed loop without any potential of flow interruption or reduction, because normally those are run continuously with potential of flow interruption or reduction need min flow return line.

 

Anyway, vendor would be the best reference to determine requirement of min flow line.

Can centrifugal pump datasheet did not have minimum flow value? Because some datasheet from pump's vendor they did not identify minimum flow value in datasheet.

Salapao,

 

Generally, there is an item about the minimum flow requirement of all pumps in the relevant data sheet templates in which the vendors will specify the mentioned requirement.  Hence, if the vendor won't specify such requirement in a pump data sheet, it might be that there is no need to minimum flow line for mentioned pump.

Thank you so much for your sharing fallah.
