I have to disagree that a special pump is necessary at all. One can simply take a 5 gallon bucket, fashion a drain at the bottom with a hose adaptor, buy the valve and use gravity to feed the fluid into the tire. This works just fine.
You raise the tire up off the ground, remove the valve stem and hook up the special valvel. Place the tire valve at 12 o'clock and fill to the valve. Fill the tire to not less than 75%, basically up to the valve should do. That leaves a small space at the top for air. After removing the special valve and replacint the valve stem, fill the tire to recommended air pressure, you're done.
Just remember to be careful when you let out the air not to move the tire on the rim so you don't break the bead. You can let all the air out without losing the bead, but you can also put the special valve on when most, but no all of the air is out of the tire. If you lose bead, you can put the stem back in, and work the tire, with help, back to bead and repeat the process.
It's not really hard to do.
