Scoopwheel
A Scoop wheel or Scoopwheel pump is similar in construction to a water wheel, but works in the opposite manner: a waterwheel is water-powered and used to drive machinery, a scoop wheel is engine-driven and is used to lift water from one level to another. Principally used for land drainage, early scoop wheels were wind-driven but later steam-powered beam engines were used. It can be regarded as a form of pump.
