Abstract
The multiple-unit pump of this invention has two coaxial pumps each including a rotatable body. One of the bodies is mounted for rotation on a stationary shaft; a second shaft extends through the stationary shaft and carries intermediate the two rotatable bodies a coupling member which rotates with the second shaft and which is provided with recesses into which projections on the two bodies extend, so that the bodies are caused to rotate when the second shaft is rotated.
