Liquid application with non-contacting application system

With WEKO-Fluid-Application-System (WFA), consisting of WEKO-FLOW with WEKO-SIGMA, liquids can be ideally applied. The coating can be applied precision-metered and reproducible at any time through spray application. What's more, the modular system can be adjusted flexibly enough to be profitable also with very small production runs.

This is how it works

The WEKO-FLOW Liquid Supply Unit provides the WEKO-SIGMA rotor carrier with the desired amount of liquid and controls the entire system. The frequency-controlled rotary pump transports the liquid from the storage tank to the rotor carrier. Through the rapid rotation of spray disks, the so-called rotors, a defined stream of micro-droplets is formed; they create a uniform liquid application. The application volume is thereby adapted to the machine speed. Liquid not sprayed can be returned to the storage tank of the Supply Unit.

Convincing in handling and maintenance

The modular units WEKO-FLOW and WEKO-SIGMA were tuned to the use of a variety of fluids. Retooling and cleaning times, especially in regard to the use of chemicals, are therefore minimal. All components can be handled conveniently during operation and maintenance and feature a long service life.
