Dellmeco - Metal Air Operated Diaphragm Pumps (AODD)
DELLMECO air operated diaphragm (AODD) pumps are suitable for a wide range of applications. They have a high abrasive resistance and withstand aggressive chemicals including acids, oils, solvents, paints, sludges and even media containing solid particles such as found in waste water. These pumps can also be used for transferring powders.
All the pumps are self-priming and the capacities and pressure can be easily controlled.
This pump is a positive-displacement pump that transfers fluids by means of diaphragms movement operated by compressed air.
The casing in contact with the fluid is made of the following material versions: Aluminium (code: A..-X), Aluminium coated with PTFE (code: B..-X), Cast Iron (code: C..-X), AISI 316 (code: S..-X).
