A pump is provided that includes a body made at least partially of an elastomeric material and an inlet port and an outlet port, with each port being coupled to the body. The pump further includes a flow passage formed in the body and extending between the inlet port and the outlet port, with at least a portion of the flow passage being normally closed and with the inlet port being fluidicly uncoupled with the outlet port when the pump is in a free-state condition. An actuating device is coupled to the body and is operable for sequentially deforming the body to create a cavity within the normally closed portion of the flow passage, the cavity being in fluid communication with the inlet port, thereby drawing a packet of fluid from the inlet port into the cavity and propagating the cavity and the packet of fluid contained therein toward the outlet port.

A shuttle valve () is provided having a body () defining an interior chamber (). The valve () includes inlet (), outlet () and common () ports that are coupled to the body (). A shuttle () is translatably disposed within the chamber () between a first position wherein the inlet () and common () ports are fluidicly coupled and the common () and outlet () ports are fluidicly uncoupled, and a second position wherein the outlet () and common () ports are fluidicly coupled and the common () and inlet () ports are fluidicly uncoupled. A first check valve () coupled to the inlet port () to permit fluid flow through the inlet port () into the chamber () and to prevent fluid from discharging therethrough. A second check valve () is coupled to the outlet port () in a manner to permit fluid to discharge from the chamber () through the outlet port () and to prevent fluid from flowing through the outlet port () into the chamber ().
