RAASM air-operated diaphragm pumps are ideal for a wide range of uses and are arranged for numerous applications.

The air-operated diaphragm pumps are oscillating transfer pumps with 2 opposed pumping chambers. Each chamber is divided into 2 hermetic parts, one for the air and one for the fluid. The 2 membranes are united by a metal shaft that forces the membranes to carry out an alternating motion. The introduction of air into one part of the chamber creates suction of the fluid in the opposed part of the other chamber
and vice versa.
