Abstract

Bekannte Zisternenpumpen mit Motorantrieb bestehen aus einem Elektromotor und einer unterhalb des Motors angeordneten Druckpumpe. Für eine Absaugung ohne Störung der Schichtenbildung wird vorgeschlagen, daß die Druckpumpe 1 seitlich einen Sauganschluß 2 aufweist, der mit einem im wesentlichen horizontal ausgerichteten Paßstück 5 mit definierten Anschlußöffnungen ausgestattet ist.

Figure 00000001
Known cistern pumps with a motor drive consist of an electric motor and a pressure pump arranged below the motor. For suction without disturbing the layer formation, it is proposed that the pressure pump 1 have a suction connection 2 on the side, which is equipped with an essentially horizontally aligned fitting 5 with defined connection openings.
