WHEN TO USE IT

The GVC-type vertical chain screen of the is suitable for the most varied screening needs, in terms of the dimensions of the channel, the flow rates and the filtration openings. Indeed, GVC is SERECO’s best-selling screen and is the one that has undergone more frequent and continuous restyling over the years to meet improvements in functionality, in expected life cycle, in energy consumption and in quality to deliver up to the perfect machine of today.

HOW IT IS MADE AND HOW IT WORKS

This type of screen consists of a cold-bent steel sheet frame on which the guides for the special roller type chains are set. The toothed wheels for the movement of the chain are fixed only at the upper end of the machine. Indeed, in the lower part of the screen the chain is wound directly around static returns. This prevents moving mechanical parts from being immersed in water, ensuring reliability and durability over time. The cleaning of the filtering screen is ensured by one or more rakes mounted on the double chain which provide for the recovery of the screened material held on the bars. A comb-cleaning device with oscillating movement ensures the cleaning of the rake, improving the fall of the screened material into the underlying hopper. The movement of the machine is done by to a sturdy gearmotor and protection against overloads is guaranteed by standard dynamometric devices or by electronic absorption limiters upon request.
