Vertical perforated cylindrical strainer

A vertical perforated cylindrical strainer is installed directly in the pond to allow water circulation while preventing fish from leaving the pond through the pumping pipeline. It is designed to provide water intake over the entire depth of the pond, ensuring uniform extraction without creating stagnant zones or hydrodynamic stress for the fish.

• Main function: filter water by retaining fish and solid debris while maintaining a steady flow to the pump.

• Positioning: vertical, submerged in the pond, usually at the entrance of the pumping pipe.

Typical features

• Materials: stainless steel, PVC, or polypropylene, resistant to corrosion and water.

• Perforations: holes sized to retain fish while allowing water and fine particles to pass.

• Diameter and height: adapted to the pond’s water flow and the size of the fish.

• Maintenance: removable for cleaning or replacement.

Advantages in aquaculture

• Fish safety: prevents fish from being sucked out of the pond.

• Uniform intake across the entire water depth to reduce stress and clogging.

• Protection of pump and piping against debris.

• Simple and robust installation, suitable for ponds, tanks, and recirculation systems.
