Hi all, I am in the process of purchasing pump for 10 hL (8.5 bbl) brewhouse and it would be great if someone could check my numbers before final decision.
Pump will be used as wort transfer and CIP pump.
After reading everything I could find I managed to calculate required flow and head, probably wrong but numbers are:
FLOW: Flow rate (l/h) = diam (m) x 3.14 x 1490 = 1.5 x 3.14 x 1490 = 7 m3/h (1856 gpm)
Calculated based on this article (page 10):
HEAD: pressure drop in static CIP head (1.5bar) + tank heigh = 15 + 2= 17 m (56 ft)
I know everyone is suggesting CPE pumps but they are not easily available in EU, so my options that suit above needs are Ebara DWO/E 400 and Lowara CO 350/15/D with these specs, both with VFD:
Ebara DWO/E 400: 4 hp, open impeller, 1.5" input, 1.25" output
Lowara CO 350/15/D: 2 hp, open impeller, 2" input, 1" output
Diagram comparison:
What would be your choice between two and is there something I am overlooking?
What seal do you suggest for CIP (viton, epdm..)?
Thank you for any help!
