The invention relates to a mixer insert having a support rod element and at least one vortexing element and a rotary drive connection structure, wherein the mixer insert, for insertion into a tubular passage element, and together therewith, is adapted to a device for mixing at least two fluid components to be placeable by means of the rotary-drive connection structure in drive connection with a driveshaft of the device, when the mixer insert is inserted into the passage element and the passage element is placed in fluid-tight flow connection with at least two component feed lines of the device, characterized in that the rotary-drive connection structure has a bore hole having a bore hole wall which are adapted to a thread on the driveshaft in such a manner that the bore hole, for producing the drive connection, can be screwed onto the thread, wherein the bore hole wall is shaped by the thread. The invention also relates to such a device for mixing and also to a system of such a device and such a mixer insert.

A two-component pumping system includes a first pump for pumping a first component, a second pump for pumping a second component, a motor, and a yoke assembly for connecting the motor to the first pump and the second pump and driving them simultaneously. The first pump includes a first displacement rod that reciprocates in a first pump axis. The second pump includes a second displacement rod that reciprocates in a second pump axis parallel to the first pump axis. The motor includes a drive shaft configured to reciprocate in a drive axis that is parallel to and in a common plane with the first and second pump axes. The motor is also configured to drive the first and second displacement rods in unison. The yoke assembly includes a top connector and a shoe. The top connector connects to the drive shaft.

Silicone dispensers are provided that include a first flow path that includes a first mixing tank, a first pump, and a first mix head inlet, and a second flow path that includes a second mixing tank, a second pump, and a second mix head inlet.

A fluid directing flow manifold for directing reactive fluids, independent of one another, from a dispensing manifold to a dispensing tip of a fluid dispensing apparatus provides a disposable and low cost fluid passageway between the dispensing manifold and dispensing tip while reducing or eliminating the possibility that reactive fluids will react and clog or block the dispensing manifold. The flow manifold provides independent fluid passageways between valves of a dispensing manifold and a mixing chamber of a dispensing tip of the dispensing apparatus. The flow manifold may be adapted for use with various types of fluid dispensing systems. The flow manifold may include multiple fluid guide bodies that may each be removed from the flow manifold to be cleaned or disposed of, and then replaced. Quick release mechanical fasteners are included for quick attachment of the manifold to a dispensing manifold valve and to the dispensing tip.

A system and method for forming a polyurethane foam includes supplying an isocyanate component from a source of isocyanate to a proportioner. A resin component from a source of resin is supplied to a metering unit and an additive having an unstable state from a source of additive is supplied to the metering unit. The resin component and the additive form a reactive mixture when combined. The system and method includes delivering the reactive mixture by the metering unit to an accumulator and storing the reactive mixture in the accumulator. The system and method further includes demanding a supply of the reactive mixture with the proportioner and supplying the reactive mixture by the accumulator to the proportioner and mixing the reactive mixture with the isocyanate component by the proportioner to form the polyurethane foam.

The invention relates to a method of injecting polyurethane, where the contents of two cylinders (2) of polyol and isocyanate are mixed in a static mixer (3). The mixed amount of polyurethane is injected with a gun (1) into a hole and at the appropriate points for joining the fittings. The injection can be done in horizontal hanging lines that run through the roof, in vertical columns, but also in any other case as judged by the applying person.

A device and process for applying a quick dry rapid set aqueous solution. An indicator of a selected color and composition is added to an accelerator to be applied along with a resin. The tinted color indicator is typically blue and allows the user to determine if the proper mixture is being applied. The indicator is visible only during application and disappears after application. The resin and accelerator are applied using an airless spray mechanism with delivery systems and spray gun. The spray gun has 2 nozzles and the capability to set the angle between the nozzles.

A dynamic mixer dispense valve and metering apparatus suitable for use in mixing and applying high viscosity, disparate viscosity, high ratio and/or relatively immiscible two part compounds that exhibit short cure times includes a housing supporting a pair of valve assemblies each coupled to respective sources of base and accelerator components. A pair of pneumatic valve actuator s control the operation of the valve assemblies to control the flow of components into a mixing chamber. Within the mixing chamber a mixer impeller is rotatably supported and coupled to a source of rotational power. An additional pneumatic valve actuator combination operates a further flow control to prevent undesired material loss following a shot cycle.

A fluid delivery system includes a status indicator and control system comprising a processor. The processor is configured to receive a first signal indicative of a first status of operations of a spray application system. The processor is further configured to provide to an operator of a spray gun, via a display system, a visualization representative of the first status of operations, and techniques to control the fluid delivery system, wherein the spray application system is configured to deliver at least one fluid to the spray gun during operations.

A method and system for the spray application of epoxy materials is provided. The system includes a dual walled tank structure as a reservoir for containing and preheating the epoxy materials in preparation for mixing and spray application. Each component of the epoxy material is preheated before the components are mixed. After preheating, the components are then mixed together and spray applied. The method and system of the present invention provides a high quality spray applied epoxy coating while reducing equipment down time and cleaning.
