La production est pompée vers la surface par le train de tiges de production (13) en passant par une vanne de régulation de débit (32). Une pompe rapportée et amovible (24), entraînée par une tige, est raccordée de façon amovible à l'intérieur du train de tiges moteur (12). Ce modèle de pompe rapportée (24) et l'organe de régulation du débit (32) peuvent être détachés aux trains de tiges et être introduits sans qu'il soit nécessaire de retirer du puits l'un ou l'autre des trains de tiges.
