Plastic AODD pumps are positive-displacement pumps that have a diaphragm in each of their two pumping chambers. These diaphragms are connected by a shaft so that when the compression stroke takes place in one chamber during the pumping process, the suction stroke takes place simultaneously in the other chamber. This results in efficient, reliable, cost-effective, repeatable operation when handling any number of abrasive liquids or compounds. Solid body plastic AODD pumps have many advantages for abrasive-handling. They do not require electricity, they are self-priming and can pump a wide range of abrasive media, from slurries to liquids with suspended solids.
