Our pump pontoons are specially designed with a low-roll centre to avoid problems with tipping and roll over (see PDF labelled ‘CSI’ attached on dangers of poorly designed pump pontoons).
The centre of the structural steel frame of the pump pontoons have a low-slung chassis (gull wing design as shown below) to ensure the pump base sits below the deck of the pontoon. This lowers the centre of gravity for increased stability and also prevents the pump sliding on the pontoon which otherwise may cause load imbalance, tipping or roll over.
The floatation modules are fitted with top entry inspection ports and are ballasted with a weighted keel for increased roll-over stability and filled with a closed-cell polymer foam to make the floatation modules unsinkable even if the rotomolded surface layer is breeched or damaged. The float systems are sized so that buoyancy of the whole pontoon exceeds total pump assembly weight by 250 kg minimum.
