20mm pipe flow rate

Hi guys,
I purchased a 1100 lt tank last week and in the process of building a sump for it.
Will 20mm pvc pipe cope with the flow rate or should I go bigger, if so what size?
Any help or suggestions greatly appreciated

go with 40MM, 40mm would handle up to about 5000 L/hr

if you could read dutch or want to translate it.
my reply is based on this

and one in English as well, but with imperial values and not metric..

I might be dutch but I don't have a dutch scape.
