Understanding pump pressures calculations

Understanding pump pressures calculations

Understanding pump pressures calculations

(OP)
Hi All,
I have a case in which I am bit confused, in the pump data sheet its mention flow is 85.2m3/hr
TDH: 24.35M
Now suction pressure at normal is flow rate is : 42.21 bar (abs)
And at max suct pre @shutoff is 24.35 bar (abs).
Now isn’t it wrong mention from client, how can be the suction pressure @ max be low then at normal conditions, I am attaching the page for more clear view
Note specific gravity is 0.8

RE: Understanding pump pressures calculations

Looks like a mistake. Probably not a coincidence that
Differential Head is 24.35 and max suct pre at shutoff = 24.35 barg
Print the whole sheet.
