Hi Michael ,

Really any side tank or tender pump for a 5 inch gauge engine would serve . There have been many good and bad designs published but most of them basically functioned .

I'm in the process of building a boiler test rig Mike, although it's not quite finished. I generally based my pump on the design published in EIM May/June 2009. I modified it to use what I had available (brass pump body, aliminium block and stainless steel handle & ram ect. It uses O rings in the valves rather than trying to seat a stainless ball effectively. I found it easy to size the pump to suit the materials to hand and apart from my time – it's cost me nothing. Regards, IanT

Michael ,

I've made several attempts to upload a drawing and article for you relating to a quite nice handpump but on each occasion this site's software has lost interest part way through transmission and locked up .

Send me an Email address via pm's and I'll send direct if you still want it ..

Michael .
