You are not going to find a good high pressure and high volume portable single pump to carry on a bike. It takes more effort to push down on the pump rod on a high volume pump when used for high pressure. Consider getting a second pump. Or a really long one that moves a lot of volume per stroke that has a small enough diameter to supply the high pressure.
Several years ago we often got questions on the touring forum about which was the best pump for touring. I eventually got around to writing up a lengthy post comparing the favorites.
