Diaphragm Pumps

ARO's ATEX-certified diaphragm pumps are widely used to pump various light to medium viscosity fluids in chemical processing industries and water / wastewater treatment plants. These ARO pumps feature an unbalanced valve design that eliminates the occurrence of valve centering and pump stall-out even when the inlet pressure is very low. The company manufactures metallic and non-metallic electric diaphragm pumps in different sizes, operating pressures and diaphragm materials.

Air Operated Double Diaphragm Pumps

Dayton double diaphragm pumps are suitable for general pump transfer, recirculation, spraying, dispensing, filling, fuel evacuation, low scheming transfer and rough metering dewatering applications. They feature cast iron construction for wear resistance & vibration dampening, and spring assisted air valves that do not require lubrication for rapid discharge of the media present in pipelines. These pumps can run dry and have the capability to pump solvents, slurries & high viscosity liquids such as waste oils & paints. They have NPT, flange & Tri-Clamp connections for secure seals and transportation of liquids with minimal risk of contamination. Choose from a broad range of these pumps, available in PTFE, Buna-N, santoprene (R) and EPDM ball variants.

SANDPIPER -

Double Diaphragm Pumps

Sandpiper double diaphragm pumps (also called AODD pumps) are operated by air / natural gas and used for transporting sludges, slurries, abrasives and shear sensitive fluids. The air pressure in these pumps acts along the entire surface of the diaphragm, keeping it balanced while pumping, that substantially extends pump life as compared to that of mechanically operated diaphragm pumps. Ideal for on-demand intermittent jobs, these AODD pumps can be safely dry ran & deadheaded without causing any damage to the pump or system. Self-priming and high vacuum capable, Sandpiper pumps can continuously pump fluids even if situated out of the pit and offer a maximum suction lift of 9.8 m. Also, their flooded suction feature allows for outdoor mounting of the pump & is mostly preferred for pumping viscous fluids. As they are safely submersible and utilise compressed air as their power source rather than electricity, these pumps are suitable for use in hazardous areas. Offering flow rates of 4, 42, 106 and 135 GPM, Sandpiper double diaphragm pumps are available in both NPT and flange-type connections. A screened inlet option is available for making the filtration process more efficient when the pumps are submerged under water, where sediments and debris are very common.
