Boiler feed pump
« on: November 11, 2017, 11:45:58 PM »
Hi Guys,
While reading some old issues of live steam magazine I came across an idea for a feed pump. The idea is it is steam driven like the normal shuttle valve ones, but the steam feed is taken from a boiler fitting positioned at the max water position. The idea being that when the water rises above the max level water goes through the pump instead of steam, the pump slows down until the pump line is again receiving steam. The water outlet is connected to the boiler by a clack valve, the inlet is from a hot well which also receives the steam outlet. This set up was suppose to be for the Diana model boat hull, there were plans and a kit done by steamfitter, I have seen the engine and boiler done from this kit but not the pump. I don't know if the pump was ever built or tested.
