Abstract
The invention relates to an external filtration device, particularly for aquariums and ornamental water tanks, which includes a container formed by a lower hollow part (2) that is closed at the top by a detachable lid (3) and internally accommodates a filtration chamber (6) and a pump (11) which are connected to the outside by an inlet connector (8) and an outlet connector (15). A priming suction chamber (18) is located upstream of the pressure chamber (12) of the pump (11) and downstream of the filtration chamber (6). The suction chamber (18) has a removable upper plug (25) and is connected to the pressure chamber (12) of the pump (11) by an horizontal passage (20) and to the filtration chamber (6) by a vertical duct (22). A discharge chamber (26) is located directly downstream of the pressure chamber (12) and is directly connected to the outlet connector (15). Safety hooks (27) engage the lid with the lower hollow part (2).
