Abstract: A syringe pump can be operated to produce fluid flow from a syringe installed therein. Features of the pump can produce a desired rapid commencement of flow followed by smooth delivery uninterrupted by stiction-induced slowing and acceleration. A stiff drivetrain can facilitate detection of excessive forces indicative of friction at a stopper-wall interface. The motor drive, gearing, and control parameters can enable customized acceleration patterns to determine optimal initial stage advancement to provide fluid delivery. These patterns can minimize or eliminate the delay in commencement of flow by overcoming both mechanical slack remaining and syringe stopper slack. To avoid flow irregularities produced by stiction forces in the stopper further, a mechanical vibration can be provided to the syringe and/or barrel to introduce movement of the stopper-wall interface, reducing the creation of high static friction coefficients.
