INTAKE SCREENS – SUBMERGED CYLINDRICAL DEBRIS SCREENS
The AWMA Inlet Screen is designed to eliminate debris blockages on diversion pumps from natural waterways and canals.
The inlet screen has a very low approach velocity. It's self-cleaning functionality utilises internal and external non-powered debris removal brushes to eliminate any debris loading or suspended solid buildup from the structure.
The screen material and design dictates very low maintenance requirements. The Inlet Screen is manufactured from 3mm slot Grade 304 stainless steel wedge wire. The screen is self-cleaning, requiring no external power source or water supply to clean the screen. The cylinder is cleaned by one exterior static, and one internal rotating brush that operates automatically whenever the flow in the suction pipe exceeds 0.6m/s, turning an impeller that rotates the screen through a gearbox arrangement.
When fitted to a submersible pontoon the inlet screen is bolted on to a 304 stainless steel frame that is mounted between the two poly pontoons.
