ANORDNING VID EN PUMPFORSEDD BEHALLARE FOR PUMPBART MATERIAL

摘要

The invention relates to an arrangement in containers (1) intended to hold materials of a pumpable consistency. The arrangement comprises a reversible motor (9) which is drivably connected to a rotatable agitator (12) located in the container (1). The arrangement is characterized in that there is arranged between the agitator (12) and the pump (2) a coupling means (11) adapted to couple the agitator to the pump when the agitator is driven in a first rotational direction, and to hold the agitator disengaged from the pump when the agitator is driven in a second rotational direction, opposite to the first.
