variomix: polyurethane mixing system
The variomix is a 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.
These modern metering systems can be used in any industry where materials need to be applied in a high precision and repeatable way:
- Automotive
- Electrical and electronic
- Renewable energy
- Aerospace
- White goods
Typical Applications
- Coating
- Encapsulating
- Gluing
- Laminating
- Sealing
Features and Benefits
- Simple operation
- Variable mixing ratio
- Variable output rate
- Continuous flow rate
- Solvent free
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.
Flow rate: up to 2 l / min with A1, depending on mixing ratio & viscosity
up to 8 l / min with A2, depending on mixing ratio & viscosity
Mixing ratio:
100 : 100 to 100 : 10 (A1)
100 : 100 to 100 : 6 (A2)
Maximum working pressure: 200 bar
Material supply: Pressure vessels (6 to 120 l)
Viscosity range: 50 to 80,000 mPa s, with pressure vessel
up to 1,000,000 mPa s, with drum pumps
Material characteristics: Unfilled, filled, abrasive
