DEF

A motor-actuated pump.

CONT

Hydraulic Systems for Wide-Bodied Airliners. ... A backup means of pressurizing all systems is provided by two electric motor-driven auxiliary pumps and two hydraulically operated, reversible motor pump units. The electric motor-driven pumps pressurize system 3 only. The reversible motor pump units, by means of a mechanical linkage in each unit, permit system 3 to pressurize systems 1 and 2 or be pressurized by either system 1 or 2. The two motor pump units mechanically connect system 1 with system 3 and system 2 with system 3 and are completely separate hydraulically. Each motor pump is hydraulically controlled by two electrically operated, motor-driven shutoff valves that operate simultaneously.

Ensemble d'un moteur thermique ou électrique, d'une pompe et de ses canalisations d'aspiration et de refoulement.

CONT

Alimentation au moyen de moto-pompes électriques. Les eaux condensées sont recueillis dans une bâche où elles sont reprises par une pompe qui les réintroduit dans la chaudière. [...] Retour des eaux condensées au moyen de vapeur. [...] Ces deux types d'alimenteurs [alimenteurs sous-pression et alimenteurs sous vide], fonctionnant sous l'action de la vapeur, doivent être attentivement surveillés. [...] Le principal avantage qu'ils offrent par rapport aux moto-pompes alimentaires, réside dans le fait qu'ils ne dépendent, en aucune façon, de la fourniture du courant et que leur coût d'exploitation est peu élevé.
