Get one that uses a diaphagm pump. This type only produces gentle pressure and won't force more air if it meets much resistance - ideal for this sort of thing.
If you can't find out for sure you can check by running the pump and putting your finger over the outlet. The pump keeps running and applying gentle pressure but won't keep increasing to the point where it forces air past your finger.
In other words, by the way this type of pump works it will just start spinning it's wheels, so to speak.
