An implantable drug infusion device includes a pump tube for holding a liquid to be pumped. A race is configured to support the tube. A roller assembly is configured to compress the tube against the race at one or more points along the path, and the roller assembly includes at least one roller. A drive assembly drives the roller assembly relative to the tube along the path so as to move the liquid through the tube. A biasing member is operably connected to the at least one roller to bias the at least one roller against the tube.
