Media tank

A method of assembling a media tank, the method comprising:

• providing a divider at an interface between a first housing portion and a second housing portion, the divider separating an interior volume defined by the first and second housing portions into a first chamber and a second chamber, at least one of the first and second housing portions being free to translate with respect to the divider;
• friction welding the first housing portion to the second housing portion, thereby generating flash at the interface;
• preventing translation between said at least one of the first and second housing portions and the divider with the flash generated at the interface;
• and
• locating a radial protrusion of the divider within a recess defined by the second housing portion to maintain an axial alignment of the divider with the interface prior to friction welding the first housing portion to the second housing portion.

A media tank comprising:

• a housing having a first housing portion coupled to a second housing portion at an interface between the first and second housing portions, the housing having a radial recess formed at or adjacent to the interface, the first and second housing portions collectively defining an interior volume of the housing;
• and
• a divider positioned within the interior volume of the housing at the interface between the first and second housing portions, the divider having a radial protrusion that extends into the radial recess of the housing to maintain the axial position of the divider at the interface;
• wherein the first housing portion is coupled to the second housing portion via a friction welding process that generates flash at the interface, and
• wherein the flash forms at least a partial radial seal between the divider and the housing.
