DIN & ANSI Flanges
DIN & ANSI Flanges
(OP)
Dear Folks;
I have some Chinese manufactured pumps, one of which has 50 and 32 mm DIN style flange connections. Can anyone steer me to a good website or resource for DIN pump flange dimensions?
I have tried looking at a list of standard 50mm DIN PN6 loose flanges but the bolt circle and bolt dia dont match the flanges on my pump.
I would like to mate these things to North American ANSI flanges. Does anyone know if any of the DIN pump flange connections are straight conversions from thei ANSI counterparts ?
Many thanks in advance for your consideration

Many thanks for your advice. I tried the Sandvik link and printed the catalog. It appears the chinese pump must have a proprietary flange style because the hole dia and bolt circle still dont match DIN specs although the inlet and outlet diameter are standard DIN sizes (ie 40 and 65 mm)
The drilling idea is practical, by drilling an ansi bolt circle with holes at 45 degrees to the existing holes I should be able to bolt on an ANSI flange.
Thanks Again

Just remeber what i said with regards to nozzle loads: The flange on the punmp might be thinner and thus need an extra check with regards to nozzle loads.
Best regards

RE: DIN & ANSI Flanges
The inlet and outlet flange on the pump is stamped 304 stainless steel, approx. 2mm thick. The pump itself is a deep drawn stamping, but the wall thickness is 1.5mm
I will pass your reccomendations over to the engineer. Although it is understood that this pump will never be used for anything but light duty service and the max loads will likely never be reached.
Thanks!
Adrian
