This looks like some kind of air powered hydraulic pump. It may not be adaptable to water rockets, sadly.

Unfortunately, it isn't. I asked around at spudfiles about this and a lot of difficult work would be needed to make a pump out of it. The 600cc refers to the oil capacity. A small pump is used to pressurize the oil.
