In Charterhouse near Manor Farm. A chain pump, certainly used for pumping water, but also used on farms for pumping slurry. A chain pump doesn't use valves - and hence needs little or no maintenance - but has a series of disks on a continuous chain that are wound down into the water source and then lift the water up through the delivery pipe. Simple but effective, and is based on a design that's thousands of years old, origination in China, I think, where they tied rags to the chain. The pump in this picture has lost its chain, but you can see the chain wheel with its slots that would have accommodated the disks.
