Nice castings !

That is a nice looking pump and should look good running. The only thing that looks wring to me are the rather large flat nuts and bolts. As you say quite small but I suppose there is a trade off against cost as it looks to be the most expensive pump so a larger one would be quite costly and only a few could afford that.

Look to mostly be lost wax castings so the surface should be as good as they look and may also have been a limiting factor in size as to what can fit the flask though I suppose larger could have more sand cast parts and not do all the parts in bronze just keeping that for the actual wet parts which would help with keeping the cost down.

It would be possible to alter some sizes to imperial for example the inlet and outlet are given as M5 or M6 which would be metric fine not coarse but you could no doubt go for 3/16, 7/32 or 1/4 x 40 or 32 ME

Would be nice to find an image of the pump it was based on or it may be a mix of a few similar designs to come up with a good looking model.

Seem to be a few likely candidates on the net that may have inspired this one. MAybe Sanjay should go the opposite way with this one and make the finished engien look like a barn find rather than ppaint n polish :LittleDevil:

That's an interesting pump and some nice looking castings  :) :) :)

I expect most of the German in the drawings will be self explanatory however I (and several others on here) can help with technical German translations.

Michael S.:
I spoke with Ingo Berghammer today. He's pleased that someone wants to work on his castings. All the parts were made using the lost-wax casting process. This all takes place in his garage, where he casts aluminum, brass, or cast iron. The cast iron flywheel for my Stuart No. 9 is also his work.

The pump isn't based on a specific model. He sent me pictures of pumps that served as inspiration.
