Debris Pump is specially designed in mind to extract sand and small pieces of debris from the bottom of
the Caisson. This Pump is totally bladeless but a unique oscillator that differentiates the pressure in the
Pump carries the debris and sand along with water to the surface. The Discharge Hose is 1.5” ID. The
Pump utilises the on-board air supply which is readily available to achieve its task. No additional high
capacity compressors are required. As long as there is a minimum of 3M head water above the debris
Pump, the Debris Pump will carry the debris to the surface.
