<p>The mixer pump has a mixing drum (16) driven by a rotary drive (42) with variable revolution speed, and a buffer tank (18) loaded with liquid concrete from the mixing drum. A concrete pump (20) is attached at the buffer tank and is driven by a drive mechanism with variable conveyor capability. An upper filling level probe (48) is arranged within the upper area of the buffer tank. A control device (44) is attached at the signal output of the upper filling level probe. The concrete pump has a signal generator for indicating the operating condition. An independent claim is included for a method for operating a mixer pump.</p> |
