Hydram water pumps were first produced by Accrington engineer John Blake in the 1880's and modern versions are still made.

They work without using any power, and with few moving parts, simply by using water pressure to force water from a feed tank to a smaller outlet.

Effective for supplying water to cattle drinking troughs etc. And many other uses.

I don't know anything about the age of this unit which isn't working, although it appears to be still connected to a water supply.
