Lift Disk Pump (from Internet Glossary of Pumps)
Lift Disk Pump
This type of pump uses flat disks (shown on edge in red here) attached to a chain or rope. The disks draw water up a tube.

This type of pump is probably thousands of years old. It is similar to a Rag Pump or Bucket Pump.

(This is a still representation and possibly also a low-resolution image of a pump which is fully animated in the CD-ROM version of this glossary.)
