Title (EN) PUMP APPARATUS
(FR) APPAREIL DE POMPAGE
Abstract:
(EN) A pumping apparatus has a linear electric motor (10; 40) reciprocally driving motor pistons (16; 45) hydraulically coupled with pump pistons (25) or with coupling pistons (51) mechanically connected with pump pistons (61) which move the fluid to be pumped. For undersea use, the coupling arrangements allow convenient separation and retrieval of sub-assemblies requiring relatively frequent servicing.
(FR) Appareil de pompage comportant un moteur électrique linéaire (10; 40), des pistons d'actionnement réciproque du moteur (16; 45) accouplés hydrauliquement à des pistons de pompe (25) ou à des pistons d'accouplement (51) reliés mécaniquement à des pistons de pompe (61) actionnant le liquide de pompage. En utilisation sous-marine, les systèmes d'accouplement permettent de séparer et de retirer aisément les sous-ensembles nécessitant un entretien relativement fréquent.
