Abstract: The system includes a pump assembly comprising a pump mechanism having an inlet side that fluidly couples to a fluid supply, and an outlet side. A pressure sensor is coupled to the outlet side and configured to measure fluid pressure. An actuator is coupled to the pump mechanism. A controller is coupled to the pressure sensor and is configured with a preselected set of fluid pressure set points and one or more preselected sets of fluid flow rates and to control the actuator to increase a fluid flow rate to a first flow rate when the fluid pressure at the outlet side falls to a lower one of corresponding fluid pressure set point. The controller controls the actuator to reduce the fluid flow rate to a second fluid flow rate, when the fluid pressure at the outlet side rises to an upper one of a corresponding fluid pressure set point.

Abstract: A scrub body, a scrub anchoring system, and a method for securing and releasing a tube coupler into and from a scrub body. The scrub body can comprise two portions, or regions, within a single, unibody sponge-like material or as two similar or dissimilar layers within the sponge-like material. The scrub body includes an anchoring pocket extending into the scrub body between the portions, regions or layers, to accommodate a tube coupler releasably secured inside the anchoring pocket. The scrub body with anchoring pocket can be discarded when worn out while the more expensive tube coupler can be readily removed from the anchoring pocket and re-inserted into a new scrub body to provide the same low-flow liquid releasing tube into a new scrub body.

Abstract: Low-flow fluid delivery system. The system includes a pump assembly comprising a pump mechanism having an inlet side and an outlet side, wherein the inlet side is configured to fluidly couple to a fluid supply. The system further includes a pressure sensor operably coupled to the outlet side and configured to measure a fluid pressure at the outlet side. An actuator mechanically is coupled to the pump mechanism to drive the pump mechanism. A controller is coupled to the pressure sensor, wherein the controller is configured with a preselected set of fluid pressure set points and one or more preselected sets of fluid flow rates and wherein the controller is further configured to control the actuator to increase a fluid flow rate to a first flow rate in the preselected set of fluid flow rates when the fluid pressure at the outlet side falls to a lower one of corresponding fluid pressure set point in the preselected set of fluid pressure set points.
