Minimum Flow Values....
(OP)
Hello;
Minimum flow value increases or decreases, which one is the more avail of process???
Thanks..

Might be a good idea to expand your questions - you might know what you are thinking but we don't.
It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

I hope it would be more clear....
Thanks...

Look at other aspects such as power consumed at duty point, closeness to BEP etc
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Finger in the air, a single stage end suction pump needs a minimum flow mainly to avoid heat generation in the pump head, rule of thumb is 10% of flow ab Best Efficiency point for intermittent duty, or we recommend 20% for a metallic magnetic drive operating 24/7 x 365 days per year due to eddy current heat generation.
There are also other considerations such as hydraulic forces to consider at low flow too, but wont go into too much detail about that at this point.
Not sure if this helps at all, but thought i would throw it out there...
