Preventative maintenance AODD pumps are very reliable since they need only a few moving parts and components which will wear. They compare very favourably with pumps that have close-fitting sliding or rotating mechanisms, where the passage of abrasive slurries, for instance, can cause excessive wear to the moving parts of the pump. This can cause significant downtime and repair costs. These problems don't arise with AODD pumps since large internal volumes and flow through prevent clogging, with the dimensions of solid particles which will be pumped associated with the pump size. Key factors to think about for preventative maintenance are: • Diaphragm lifetime • Compressed air quality • Flushing of pumps after use. The diaphragm may be a dynamic seal that converts the pneumatic pressure on one side to fluid pressure on the opposite (the material to be pumped). Although the differential atmospheric pressure across the diaphragm and corresponding internal stresses are ...
