The main objective of all flush water programmes is to prevent contamination of the seals by pumped water.The flush water programme for boxes is therefore very similar to the flush water programme for mechanically sealed boxes. However there are still some obvious mechanical differences.  The most notable difference is the addition of a seal (packing) between the inlet and outlet limits. This minimises the amount of flushing fluid consumed.
