Air Operated Double Diaphragm Pumps (MA Series)

Maggio  AODDP  (MA  Series)  is a  type of positive displacement pump. It consists of two pumping chambers that are alternately filled and discharged by the movement of flexible diaphragms. Compressed air is  alternately fed  to,  and  vented  from,  air chambers  on  the  opposite  sides  of  the  diaphragms  to  create the  pumping action.  Maggio  MA  series  are  generally  used  for transfer  applications  and  can  handle  a  wide  variety  of  feeds including  sludges,  slurries,  abrasive  and  shear  sensitive  fluids. They are robust, reliable and easy to maintain.
