A fluid filtration assembly includes a filter housing having a first end for fluid connection with a fluid storage vessel. A filter cartridge is disposable within the filter housing, and a plunger pump is coupled at a second end of the filter housing. The plunger pump includes a housing having a rigid portion and a flexible portion. The flexible portion has a plunger-engaging portion for coupling to the plunger of an actuator. The flexible portion selectively movable with respect to the rigid portion via the actuator. The filter cartridge can be a hollow fiber filter. The plunger pump can be configured to induce alternating tangential flow in at least a portion of the assembly. The fluid filtration assembly can be provided as a disposable single-use arrangement.

Various dispensing devices, such as foaming soap pumps, are disclosed. The soap pump can include a fluid storage unit and a fluid handling unit. The fluid storage unit can include a reservoir that is configured to hold a quantity of product, such as liquid soap. The fluid handling unit can include a pumping assembly and dispensing assembly. The soap pump can be configured to withdraw liquid soap from the reservoir, convert the liquid soap to foamed soap, and dispense the foamed soap from the discharge assembly.

This invention is a high-volume large diaphragm which provides a pair of support sections specially configured to withstand the stresses implemented by an eccentrically actuated pushrod diaphragm pump. The pair of support sections is comprised of an interior support section and an exterior support section that are vertically offset relative to each other's placement on the wall of the high-volume large diaphragm. It is additionally anticipated that more than one pair of offset interior and exterior support sections can be provided on high-volume large diaphragms with significantly greater wall height.

A pump for a vial intended to contain a cosmetic product. The pump includes a dosing chamber with a variable volume defined at least partially by a deformable element between an initial state and a deformed state. The pump further includes a guiding rod passing through the deformable element, the latter sliding along the rod when it undergoes a deformation. The deformable element includes an outlet lip delimiting an outlet orifice, surrounding a section of the rod, and bearing in a sealed manner against the rod or deviating from the rod according to the pressure in the chamber. The rod includes means for maintaining the outlet lip bearing in a sealed manner against the rod when the membrane is in the initial state thereof whatever the pressure in the chamber and whatever the pressure around the pump.

According to an aspect, an inflatable penile prosthesis includes an inflatable member, a reservoir configured to hold fluid, and a pump assembly configured to facilitate a transfer of the fluid from the reservoir to the inflatable member when the prosthesis is in an inflation mode and facilitate a transfer of the fluid from the inflatable member to the reservoir when the prosthesis is in a deflation mode. The pump assembly includes a pump, a valve body having a first valve and a second valve, and a selection member defining a lumen, the selection member being movable from a first position to place the prosthesis in the inflation mode and a second position to place the prosthesis in the deflation mode.

A high pressure pump is disclosed. The high pressure pump comprises a compression chamber having an inlet for connecting to a fluid supply to intake a fluid, and an outlet, an inlet check valve between the compression chamber and the inlet, a digital inlet valve between the compression chamber and the inlet check valve, a variable volume chamber connected to the compression chamber through a manifold and the digital inlet valve, and a plunger or piston configured to compress the fluid in the compression chamber and the variable volume chamber.

The fluid storage unit can include a reservoir that is configured to hold a quantity of product, such as liquid soap. The fluid handling unit can include a pumping assembly and dispensing assembly. The soap pump can be configured to withdraw liquid soap from the reservoir, convert the liquid soap to foamed soap, and dispense the foamed soap from the discharge assembly.

A diaphragm pump includes a driving mechanism and a counting sensor. The driving mechanism includes an arm portion attached to a deformed portion that forms a pump chamber, and a crank that rotates integrally with the rotating shaft of a motor, in which the rotation of the crank is converted into a reciprocal motion to make the arm portion reciprocally move. The counting sensor is configured to use the arm portion as a detection target and alternately switch between a detection state and a non-detection state as the arm portion makes the reciprocal motion. It is therefore possible to provide a diaphragm pump capable of detecting a discharge flow rate using an inexpensive ready-made motor.

A diaphragm pump includes a driving mechanism including a crank body fixed to the rotating shaft of a motor, a driving shaft that is fixed to the crank body and inclined, and a driving body rotatably supported by the driving shaft via a bearing member. The driving body includes a shaft portion that stores the bearing member, and an arm portion connected to the deformation portion of a diaphragm. The bearing member includes a first bearing member close to the crank body, a second bearing member spaced apart from the crank body, a shaft hole in which the driving shaft is rotatably fitted, and an oil reservoir formed at a boundary between the first and second bearing members. The shaft hole includes a through hole formed in the first bearing member, and a non-through hole formed in the second bearing member.
