Is the pull of a black hole perpetual?

The pull is caused by gravity, and there's no reason to believe that gravity will ever stop working.
On the other hand, black holes do eventually decay/evaporate (according to Stephen Hawking), so the black hole itself is not perpetual - and when it's gone, so is its pull.

"Perpetual" means lasting forever. All matter continues to exert a gravitational effect on all other matter in the universe, and black holes should not be an exception. I don't know of any phenonmenon that would cause a particle to stop exerting gravity, or that would put a finite time limit on the gravity of any particle.

Yes, because the pull brings more mass into the same volume, causeing the density to continually increase within the same space. This continues to increase the gravitational pull of the black hole, which brings more mass in. (Repeat over and over and over)
