PUMPING BLOCK DEVICE HAVING AN INTEGRATED BYPASS CIRCUIT

摘要

The present invention relates to a polyphasic pumping block device (110) comprising a pump (110) suitable for pumping a pumping fluid and a bypass circuit (157). Said bypass circuit is suitable for enabling the flow of a fluid from an area upstream of the pump to an area downstream of the pump by bypassing the pump. The latter comprises at least one non return valve (113) suitable for blocking the flow of the fluid from the area downstream of the pump to the area upstream of the pump. In addition, the pumping block device is suitable for being connected to a set of pumping circuits, said set of circuits comprising a main bypass circuit (152) suitable for enabling the flow of a fluid from an area upstream of the connected pumping block to an area downstream of the connected pumping block by bypassing said connected pumping block. Finally, the pumping block device is arranged in order to be disconnected from said set of circuits for maintenance.
