The variomix A/H are pneumatic driven piston pump type metering and mixing system, used to handle low to high viscosity multi component media such as epoxy resins, polyurethanes or silicones. They can be unfilled, filled as well as abrasive. The system is built in different configurations.

Function
Pressure vessels, mounted onto a portable chassis, are used to supply the material into the piston type metering pumps where they are proportioned at the pre-selected ratio. The pumps are driven by an air motor. The stroke of the air motor is transferred to the pumps via a lever system. The mixing ratio can be infinitely adjusted between its limits by means of the lever system. The system is controlled by a metering
computer.
The variomix A is fitted with a static mixing system that includes a 2K valve combined with a disposable
static mixer. The valve contains an infinitely adjustable «snuffer» effect to avoid dripping after metering has finished. Should mixed material be allowed to cure in the mixer, it can be replaced simply and inexpensively, thus avoiding a time consuming, expensive and environmentally damaging flushing cycle.
