Design for prototype steam powered pump

I wish to build a small prototype of a steam powered water pump. Eventually I intend To build a full sized pump and the prototype is the first step. Requirements: - The pump needs to be steam powered. In the location where the final pump will be used firewood is in plentiful supply and it will be the energy source. For the prototype the fuel source can be whatever is easiest, e.g if it's easier to use a gas canister rather than wood that's acceptable, - The prototype pump needs t be something I can build by sourcing parts from a 3d printer, hardware stores or online. I will require a parts list so that I can easily get the components without having to work out how to connect this piece to that piece etc. ideally it needs to be close to a lego construction set with instructions, - The final pump will need to move water from a lower dam to a higher dam approximately 500m up a steep hill. For the prototype it is sufficient to move water from a bucket in the ground to a bucket on a 1m high table, - For this task I require a digital design, the format doesn't matter, a parts list and assembly instructions.
