FILTRAMAS - Model PR -Screens
The PR Screen is specifically designed for installation in deep channels or manholes, with a minimum span of 10 mm for front cleaning and 15 mm for counterflow cleaning. It is capable of lifting large quantities of solids and very large solids, making it suitable for use as a coarse coulter in difficult locations with large amounts of water and/or very deep wells.
The PR Screen drive assembly consists of a motor reducer unit with brake, which drives directly to a transmission shaft supported on bearings. On the drive shaft there are three corrugated drums, made of carbon steel or cast iron, on which the cables are wound.
The outer cables provide the cleaning trolley with the up-and-down movement, and the intermediate cable is used for the closing and opening maneuver of the cleaning trolley, which is achieved by a linear actuator that shortens or increases the pull of the intermediate cable of the trolley. This actuator can be pneumatic, hydraulic or electric depending on the case.
