You have to make the movement dependent on the passed time. That is, measure the time using sf::Clock and multiply the velocity vector of your object with it.

Alternatively you use a fixed time. A simple way to achieve this is setting the framerate limit or enabling v-sync in sf::RenderWindow. Before you ask how to do this, have a look at the documentation.
