12" Vertical steam pump Casting set

In these three pumps the layout is the same, having the steam cylinder at the top and the water at the bottom, all working on the same principle. In the steam chest there are two slide valves, the first one operated from the piston rod which passes steam to a shuttle. This shuttle has the second valve attached to it and controls the steam in and out of the cylinder. This is a reliable method of operating the pumps and is self starting from any position. They can be run at a fairly high speed, or slowed down ‘till barely moving. They are all suitable for either steam boats, locomotives and stationary steam plants. On the first sheet of the drawings there is an assembly with all parts itemized along with a parts list. The other sheet or sheets shows details of all the parts to be made.

12 inch pump

This pump has been designed for full size steam boats and similar applications. The water end is divided into two main castings, the cylinder and valve chamber. This makes for ease of machining, also the water ways are drilled which ensures correct position, size and no sand inclusions. The bosses are big enough to take  ½ inch BSP fittings. The valve chamber top cover with the water outlet can be fitted, at the construction stage, either way. Also with the cover removed all four valves can be taken out for inspection.
