Abstract: A compression pump has a bladder that is supported during the compression stroke on the low-pressure side of the bladder, and that can have a compression cavity that is fully evacuated during each stroke. The compression pump can have a housing with an entrance section, a center section, and a crown section. The entrance and center sections define seats to receive bridge bearings (of bridges each having a rod and a bearing). A piston can have an inlet section, a middle section, and a head section. The inlet and middle sections define seats to receive groove bearings. The bridges and groove bearings structurally hold a support structure, which supports the bladder. The support structure can be a slide support that changes shape as the piston moves within the housing. The piston head can have a valve seat that the inlet valve head is received within when it is closed.

Abstract: An all-polymer reciprocating pump (100) is contemplated. The pump body (160) receives a sliding insert (170) that may be locked in a down position to minimize the extension and profile of the actuator (120) while the pump (100) is not in use (e.g., for purposes of shipping in e-commerce). Projections (171) slide within guides (181) formed on an insert housing (180). Even in this down locked position, minimal compression is applied to the biasing members (130) so as to avoid fatigue, wear, and/or failure of the plastic components.

Abstract: A pumping cassette including a housing having at least two inlet fluid lines and at least two outlet fluid lines. At least one balancing pod within the housing and in fluid connection with the fluid paths. The balancing pod balances the flow of a first fluid and the flow of a second fluid such that the volume of the first fluid equals the volume of the second fluid. The balancing pod also includes a membrane that forms two balancing chambers. Also included in the cassette is at least two reciprocating pressure displacement membrane pumps. The pumps are within the housing and they pump the fluid from a fluid inlet to a fluid outlet line and pump the second fluid from a fluid inlet to a fluid outlet.

Abstract: A fluid energy machine for imparting energy to a fluid. A channel contains a fluid flow. A flexible membrane extends the length of the channel and has a width generally corresponding to the inside width of the channel. A drive actuator at the input end of the channel imparts an activating force to the membrane at the input end of the channel, causing a transverse wave to propagate along the membrane and drive fluid through the channel.

Abstract: A unit configured as constituent part of a fuel cell for use in novel electrochemical hydrogen compressor material technology system includes a combination of a hydrocarbon auto-thermal reformer, a water-gas shift reactor, and at least two countercurrent flow heat recuperators at least one of which is downstream from both the reformer and reactor. Optionally, two of the at least two recuperators are separated by the reactor to generate H2 in addition to that already contained in reformate formed at the reformer. The unit may include a proton conducting membrane that includes an inorganic polymer with pores filled with an organic polymer, each of which is configured to operate individually within a wide range of temperatures with no added solvent.
