DIN 2533 Flanges?

[slickstyles5]

Hi,
I work using the Imperial System of units and now I need to adapt to pump with a metric flange. The details of the flange are given by DIN 2533, PN16/DN100. I know it is 100mm nominal size but now I would like to put a flange to bring everything back to imperial after the pump. Does anyone know where I can find details of this flange such as bolt circle, od, id, etc?
Thank you,
Gabriel

The old DIN 2533 is now named ISO 7005-2/PN 16.

Take a look at the attached paper

Does a PN16 and PN20 flange have the same dimensions?

Are the threads NPT?

DIN 2633 was replaced by DIN EN 1092-1 but is still common.

DIN 2633 is only applicable for PN 16 flanges. DIN 2634 covers PN 25 flanges. There is no PN 20 welding neck flange rating. See attached brochure. There you will find all the dimensions you need.

The threaded DIN FLanges have an NPT Center?

din 2533 flanges are weldingneck flanges,
What are you talking about threaded?

What happens is my pump has a DIN 2533 flange and then I would like to bolt a DIN XXXX Flange with a threaded female center (NPT Ideally). Does that exist?

You are talking about a dn100 flange and you want to connect a threaded pipe, what size?
Is it the suction or discharge?

You are too vage to answer this question.
Please be more clear.

Greetings

It is for both the discharge and suction and yes I want to connect a pipe. The pipe size is 3" Male Pipe Thread (NPT) on the discharge and 4" Male pipe thread (NPT) on the suction. I just want to know if they make such flanges? I will just call a DN100, PN16, with threaded NPT female center if it exists.

I don't know a pipespec. that uses this and I shouldn't do it that way.
But if you still want to do it that way;
Take a blindflange, drill a hole in it, and weld a (half) coupling npt to it.
