I think it will pump air, but given that it is a displacement-type pump, you will only get the same volume of air per stroke as you would get when pumping water. One stroke might give you a litre or so, but there are a lot of litres in a tender. I’m not sure about the effect of pumping for a long period “dry”. It might cause the rubber diaphragm to heat up. (This may not matter in a gas emergency on a yacht, but it might cause faster wear and tear. Why not ask the manufacturer?)
