These are an old type of valve called a woods valve. you can use a presta valve pump to pump them however it would be easy to change them to Schrader valves as recommended.
It's a "dunlop" valve. Also called "woods". I used to see this years ago in BMX bikes. For best results we'd use to have a schrader adapter (google: dunlop to schrader adapter) so we could inflate with schrader pumps.
