Yes, when a submarine boat pumps water out of its flotation (not floatation) tanks, the submarine should rise.
The density will rise and submerge the submarine.
When the tanks are full of water they force O2 out of the tanks. Once the tanks empty out the water they will fill with gasses that in the water such as O2 or Co2. These gasses are palpably less dense than water so the submarine rises. I hope that helps.
To rise again, the submarine's weight must be decreased. Air is pumped into the ballast tanks to force the water out. The buoyant force acting on the submarine now exceeds the submarine's weight. With positive buoyancy, the submarine rises. The less weight an object has the more its density decreases. Hope that kinda helps?
A submarine pumps water out of its flotation tanks to decrease its overall density, allowing it to become buoyant and rise to the surface. By removing water, the submarine reduces its weight relative to the volume of water it displaces, which is governed by Archimedes' principle. As the submarine's density becomes less than that of the surrounding water, it ascends. This process is crucial for maneuvering between underwater and surface positions.
Because the tanks are filled with air afterwards. Air has a lower density than water.

Increases
the overall density goes up.
