An engineered pumping segment for facilitating efficient and accurate peristaltic pumping of fluids, providing regulation of fluid flow and providing an effective interface for sensing fluid line pressure in a peristaltic pump system. The engineered pumping segment includes an elastomeric membrane sandwiched between a rigid base and a rigid cover and a slider adapted to slidably mount about the base and cover. The membrane and base define a channel for fluid flow and the membrane, base and cover cooperate to facilitate peristaltic pumping of fluids through the engineered pumping segment and to provide a pressure sensing interface, and in combination with the slider, cooperate to regulate fluid flow.

A dispenser includes a spout attached to a fluid-filled bag and a socket that is removable attached to the spout. Valves in each of the spout and socket are biased closed but are opened when the socket is latched onto the spout, thereby providing a fluid path from within the bag to the outside. Keying components are provided on each of the spout and socket in order that a fluid connection between them is made only when the key elements match. The valve within the spout extends into the bag when opened and may include a sharp bag wall piercing portion.
