A pump (100) is provided comprising an internal power fluid column (140) and a transfer piston (120), which is reciprocatingly mounted about the power fluid column (140). The transfer piston (120) defines a product fluid chamber (130), located above the transfer piston valve (126), and a transfer chamber (110), located below the transfer piston valve (126). The power fluid column (140) comprises at least one passageway (146), which allows the fluid inside the power fluid column (140) to be in communication with a power fluid chamber (150). The power fluid chamber (150), the transfer chamber (110) and the product chamber (130) are located coaxially about the power fluid column (140).

Une pompe (100) comprend une colonne hydraulique interne (140) et un piston de transfert (120), qui est monté, de manière à pouvoir être animé d'un mouvement alternatif, autour de la colonne hydraulique (140). Le piston de transfert (120) définit une chambre fluidique de produit (130), située au-dessus de la soupape (126) du piston de transfert, et une chambre de transfert (110), située au-dessous de la soupape (126) dudit piston de transfert. La colonne hydraulique (140) comprend au moins un passage (146), qui permet la communication du fluide à l'intérieur de la colonne hydraulique (140) avec une chambre hydraulique (150). La chambre hydraulique (150), la chambre de transfert (110) et la chambre de produit (130) sont situées coaxialement autour de la colonne hydraulique (140).
