Abstract
This specification describes technologies relating to a pump for dispensing precise quantities of fluids. In some implementations, a pump includes a rotatable portion including one or more recesses configured to receive one or more corresponding roller components; and a base portion including a fluid channel including an input aperture and an output aperture, the fluid channel being configured to receive the one or more roller components, and a flexible membrane that provides a seal between the roller components and the fluid channel, wherein, the rotatable portion is rotatably coupled to the base portion such that the fluid channel includes one or more portions sealed by the flexible membrane and one or more roller components and wherein rotation of the rotatable portion causes the one or more roller components to traverse the fluid channel pushing fluid trapped within the fluid channel and the membrane in the direction of rotation.
