ARO Air Operated Diaphragm Pumps

Hand-operated, self-priming hand pumps designed to dispense liquids at a controlled discharge rate of 0.95 litres. Feature a double-action piston to dispense liquid on both forward and back strokes. Available in cork-nitrile, EPDM and Viton gasket variants

Features

Dayton Double Diaphragm Pumps

• These air operated double diaphragm (AODD) pumps have cast iron construction for structural rigidity and wear resistance.
• They are equipped with spring assisted air valves that do not require lubrication for rapid discharge of the media present in pipelines.
• These air operated diaphragm pumps can run dry and have the capability to pump solvents, slurries & high viscosity liquids such as waste oils & paints.
• They feature NPT, flange and tri-clamp connections for secure seals and transportation of liquids with minimal risk of contamination.

Sandpiper Double Diaphragm Pumps

• These AODD pumps act along the entire surface of the diaphragm, keeping it balanced while pumping, which substantially extends pump life as compared to that of mechanically operated diaphragm pumps.
• They come with a flooded suction feature that allows outdoor mounting and pumping of viscous fluids.
• These air operated diaphragm pumps offer flow rates of 4, 42, 106 and 135 GPM for dispensing fluids.
• They provide a screened inlet option for making the filtration process efficient when the pumps are submerged under water, where sediments and debris are very common.

ARO Double Diaphragm Pumps

• They are ATEX-certified diaphragm pumps for medium-viscosity fluids used in chemical processing industries and water / wastewater treatment plants.
• These ARO pumps feature an unbalanced valve design that eliminates the occurrence of valve centring and pump stall-out even when the inlet pressure is very low.
