PC – Self-Cleaning Intake Screen

PC Screen knockout

Energy Savings

The continuously clean screens eliminate potential head/loss pressure and minimize pump energy usage.

No Maintenance

No manual cleaning of stationary screens, or routine system shutdowns.

Environmentally Friendly

Low-velocity operation keeps fish, mussels and clams out of pump intakes, preserving natural surroundings.

How It Works

LAKOS Self-Cleaning PC Screens offer continuous pump protection without the worry of routine maintenance.

For this to be possible, water is drawn in through the mesh screen trapping organic material on the outside. The internal backwash system rotates continuously and blows the debris off and away from the screen, allowing water to flow freely to the pump intake. This helps extend pump life and optimizes pump energy costs by limiting wear issues in the system.

 

Wide Range of Applications

LAKOS PC Screens fit natural and man-made bodies of water, including both static and moving water. Unique solutions for wet wells, side channels, and enclosed intakes are available. For centrifugal pumps, short-coupled turbines and VFD’s Flow velocities to match fish protection specifications.

PC Screens Application

Durable Construction

PC screens feature a strong, deep-ribbed, reinforced fiberglass frame with Stainless steel end caps. Available in corrosion-resistant stainless steel, algae-resistant phosphor-bronze, and epoxy coated options.
