Air Operated Double Diaphragm Pumps

Air Operated Double Diaphragm Pump (AODD Pumps) are a type of Positive Displacement Pumps. These pumps do not operate with an electric motor, but employs compressed air to function. These highly efficient pumps ensure low-pulsation and smooth flow of the fluids. Roto’s AODD pumps are also relatively economical to maintain.

Roto Pumps is one of the leading players in the field of providing Positive Displacement Pumps with top notch quality. Roto’s AODD Pumps are available in a variety of materials including Teflon, stainless steel, PVDF, ductile iron and aluminum. These pumps provide flow up to 60 m3/hr or 265 GPM and can handle a pressure of up to 10 bar or 145 PSI.
