GVC

The vertical chain screen is suitable to meet any screening requirements, according to the channel size, flows and filtering gap. This type of screen consists of a frame made from cold curved steel sheets on which the guides for the special type roller chains are machined. The geared wheels for the chain motion are secured only at the top end of the equipment while on the lower part of the screen the chain is directly wound around static return device.
This avoids that mechanical parts in motion are immersed in water, ensuring their reliability and long life. The filtering screen cleaning is carried out by one or several rakes fitted on the double chain which recover the screened material kept by the bars.
An oscillating comb cleaning device ensures the rake cleaning and facilitates the screenings fall into the hopper below. The equipment motion is controlled by a sturdy gear motor and the protection against overloads is ensured by standard dynamometric devices or, on request, by electronic absorption limit switches.
The version GVCM with 2.5 to 5 mm gaps, filtering screen made of perforated sheet metal or wedge wire bars and brush cleaning system, is available for micro-screening.
The standard construction is in carbon steel protected by hot dip galvanization. On request, it is possible to have the protection with epoxy painting cycle or the screen made in stainless steel.
