GF 40/43 flange specs

[Bow123]

I need the dimensions of a GF 40/43 flange. Where can I find it? It's for a Grunfos UP43-75F pump and I don't know if that flange is an industry standard or for Grunfos only. What does GF stand for? Thanks.

No, these are not standard flanges. They must be a special Grunfos Flange. GF likly stands for Grunfos Flange or something similar. You will have to contact Grunfos directly for information on this flange.

I would be surprised if the pump came with non-standard flanges. Check the context - I wouldn't be surprised if the use of the 'GF40/43 flange' was meant to mean 'flange on the Grunfos size 40 or 43 pump'...
