Sanitary Zero Maintenance Screen

Sanitary Zero Maintenance Screen


Lyco Manufacturing takes reliability to the next level with its Sanitary Zero Maintenance Screen design, eliminating trunnion wheels and bearings. The maintenance-free design removes the need for routine lubrication of the bearings. Lyco is known for making the most robust rotary screens in the industry.  As with any machinery, chain and sprocket drive systems still require routine lubrication to ensure optimal performance.

Suggested Applications

How it Works

The Sanitary Zero Maintenance Screen revolutionizes the screening process by eliminating trunnion wheels and bearings for a maintenance-free design. Effluent enters the drum and as the drum rotates, the suspended particles first are fed into the inner drum, which screens down to .080 inches. Then smaller particles pass through to the finer .020 inch outer screen. Removing larger particles first makes finer particle removal more effective. Major solids then exit the drum.
