I've used two of the little pumps in conjunction with two Air Tanks. I
takes 15-20 sec. to fill up the tanks and afterwards you can operate a
pneumatic cylinder every 2.5 - 3 sec. for about 15 min. while the
compressor is running coutinously.
The pumps where driven by an old 9V technics motor which directly drives
a wormgear.
