Abstract: A pump system including a prevention mechanism for preventing excessive fluid temperature buildup of system fluid. The overheat prevention mechanism includes a thermally-responsive control component made with a thermally-responsive material. The thermally-responsive control component is located in the pump system such that the thermally-responsive material is in thermal communication with the system fluid for effecting a change in temperature of the thermally-responsive material. The thermally-responsive material is configured to have an activation temperature that is a predefined amount less than a maximum operating temperature of the system fluid. The thermally-responsive control component is configured to cooperate with a pump control mechanism in the system to decrease pump output pressure in response to the thermally-responsive material being heated by the fluid to a temperature that is equal to or greater than the activation temperature of the thermally-responsive material.

Abstract: A fluid detection system includes a fluid detection sensor disposed at a fluid sensing portion of the system, and a reference sensor disposed at a reference sensing portion of the system. The detection sensor and the reference sensor are subject to at least one common ambient environmental condition, such that the detection sensor exhibits an electrical characteristic that is different from an electrical characteristic of the reference sensor when fluid contacts the detection sensor. The fluid sensing portion may be within an internal fluid passage of a conduit that is removably couplable to a fluid device. Alternatively or additionally, the fluid sensing portion may be disposed in a fluid flow path, such as a leak path, in a permanent structure of a fluid device. The reference sensor may be disposed in a location away from and/or intentionally divided from the fluid flow path. The system may include a warning system.

Abstract: Provided is a cartridge assembly having first and second cartridges sealed by an interface member having a first sealing member along a radially outer surface thereof having a non-planar geometry around the outer surface and a second sealing member along the radially outer surface having a non-planar geometry around the outer surface. The sealing members may each have a repeating, undulating, non-planar geometry around the outer surface. The cartridges have ends with matching geometries to allow the cartridges to engage in surface-to-surface relation around their entire extents to create with the interface member an air tight seal.

Abstract: A filter module includes a filter element with a ring of media and an end cap at one end of the ring. The end cap includes an annular body with a sealing member located around a surface of the body circumscribing a central opening, wherein the sealing member has a repeating, undulating, non-planar geometry. The axial, distal end of the annular body also has an repeating, undulating non-planar geometry, matching the geometry of the sealing member, and can have one or more tabs projecting axially outward from the distal end, positioned at a point of maximum amplitude of the distal end, and which are received in cooperating slots formed in a socket of a diaphragm, to facilitate positioning and installing the element into the module. The socket includes an outer wall having a matching non-planar geometry which receives and seals against the sealing member on the end cap.
