ABSTRACT:
A twin-shaft pump includes a working chamber; a first side plate and an opposite, second side plate bounding the working chamber; and two impellers accommodated in the working chamber and each having a first end face and an opposite, second end face. Each first end face is adjacent and oriented toward the first side plate and each second end face is adjacent and oriented towards the second end plate. There are further provided impeller bearings adjacent the first and second end faces of each impeller; and a pump drive situated adjacent the first end faces and being operatively connected to the impellers. A dish-shaped component is situated adjacent at least one of the end faces of at least one of the impellers. The dish-shaped component has an inner wall defining a dish-shaped cavity accommodating an impeller bearing which is in a supporting contact with the inner wall of the component. A stationarily held stub shaft is in alignment with the impeller bearing and projects into the cavity and the impeller bearing received therein for supporting the impeller bearing.
