Title: Duplex steam pump.
Post by: Michael S. on May 11, 2022, 08:32:56 AM

Hello,

I put the air compressor back into operation last weekend and made a video about steam pumps. It shows 3 duplex steam pumps. 2 are Worthington and one is an Oddesse pump. The controls are a bit different though.
Someday I'll build one as a model.

Greetings Michael

Even better to see one dancing on the running board of a Shay  :pinkelephant: it is on my bucket list.

The red pump is damaged by frost. On the water cylinder. The black pump too. But it was welded well before.
The green pump had only ever pumped oil and is like new.
I once pumped water with a slightly larger steam boiler model. Boiler to 5 bar pressure and then it started.
