Density = mass / volume. If the mass decreases, the density decreases.

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.
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?
Because the tanks are filled with air afterwards. Air has a lower density than water.

the overall density goes up.
Increases
because of density
It is not the matter of density. When inflation tank is filled with water then the weight of submarine is more than the weight of the displaced water. So submarine is in the sinking condition. As water is pumped out then weight of displaced water which is known as Buoyant force would be more than the weight of the submarine. So it would float.
