AODD ARO Pumps

Ideal for Abrasion and Solids Handling

Because it does not use rotating, sliding seals like rotary / centrifugal pumps, more process engineers look to ARO Diaphragm Pumps for handling tough abrasion applications.

From Top to Bottom, ARO's Flap Valve Pump is Your Best Abrasives-handling Choice

The ARO 2" Flap Valve Pump uses a top-suction porting design. Top suction porting is ideal for pumping abrasives and large particles because it uses gravity to assist in draining solids from the pump. Conventional high-solids pump designs uses bottom suction; forcing the pump to fight (and lose against) gravity, allowing sediment and solids to accumulate, ultimately packing out the pump.

Bolted Construction for Safe Reliability and Ease of Assembly

All ARO Diaphragm Pumps use bolted construction that process professionals demand. ARO Non-metallic Diaphragm Pumps utilise fasteners that are constructed of 300 series stainless steel for maximum chemical resistance.

  • Bolted is Safer: Bolted Construction reduces the risk of spills, environmental contamination and the attendant, mandatory reports to regulatory agencies that spills create.
  • Bolted is Reliable: Bolted Construction withstands the heavy loading that Diaphragm Pumps are subjected to, without concerns of breakage or loosening.
  • Bolted is Easier to Assemble: ARO's bolted design allows for easy positioning and alignment of parts during reassembly. This is a significant advantage over clamp-band style pump fasteners, which are difficult to align and hold together during reassembly.
  • Bolted is Less Expensive: ARO's design uses standard bolts which cost significantly less to replace. Non-standard fastening devices (such as clamp bands) are considered "wear parts" and are more expensive to replace.

ARO's Bryan, Ohio facility, where our diaphragm pumps are manufactured is registered by underwriters Laboratories Inc. to ISO 9001 Quality Standards.

ARO Diaphragm Pumps are backed by a generous 5-year warranty on materials and workmanship for your purchasing piece of mind.

ARO's Pump design and manufacturing operations have demonstrated compliance with the quality process, health and safety, technical files and multi-lingual standards set forth by the FEM (Federation Europeene de la Manutentio) for the European Union (Communities Economique)
