Floating Suctions


Liquip manufactures floating suction assemblies for use in horizontal or vertical, above or below ground storage tanks where little or no contamination can be tolerated, such as aircraft jet fuel. Since the fuel near the top is least likely to contain water or foreign particles, the floating suction assemblies are designed to float near the top of the liquid surface and draw from this near-surface, contamination-free liquid. All of our floating suctions are designed for long, trouble-free life

The main contaminant of fuel is water, which is heavier than fuel and will sink. It is therefore undesirable to extract product from a tank via the base as this will suck in water through the lines. The way this is prevented is by introducing a floating suction, which sucks product near but below the surface of the liquid. The suction may have a single arm or multiple arms, depending on the height and diameter of the tank. Other requirements including the actual product in the tank need to be assessed for suitability, especially in relation to its corrosiveness. All floating suctions are uniquely designed by Fuelling Solutions to meet your requirements.
