The Filtration station filters liquids. The filtrate is pumped from the first tank into the second tank through the filter using a knife gate valve. The filtered liquid reaches the second tank via the flap with pneumatic semi-rotary drive. The filtered liquid can be pumped onwards to the next station using a separate pump. The filter can be rinsed using a rinse program. Regulated compressed air is additionally blown through the filter to loosen deposits.

Measurement and control

Sensors detect the filling level of the container in the Filtering station. This permits lessons on simple control exercises for monitoring the pumps right up to complete control projects involving complex processes.

Pressure control ensures constantly high filter quality during flushing. The pressure sensor with LCD display, analogue output and switching output always supplies the correct measurement variable. The controller with P, PI or PID control algorithm ensures constantly high filter quality during rinsing via the proportional pressure regulator. Control technology is clearly and practically explained in this way.

Shutting off, opening, closing

The right selection of process valve, drive, drive accessories and control valve plays an important role in complex process sequences. The Filtering station uses an extremely wide range of process components. All the valve actuators are actuated via a directly connected NAMUR valve.
