A syringe pump which includes a pusher block is slidably mounted on bearings on one or more guide rails. The pusher block is advanced or retracted by a lead screw having an axis which is offset from the axis of the one or more guide rails which are supported at their respective ends by support blocks, wherein forward and/or trailing sides of the pusher block bearings are extended, and wherein the guide rail support blocks include recesses for accommodating the extended ends of the pusher block slide bearings. In another embodiment, the syringe pump includes quick connect-disconnect fixtures for loading and unloading syringes. Other mechanical, and programmable improvements are described in the specification.
