AODD Pumps: Small Design, Big Impact

AODD Pumps: Small Design, Big Impact

When reliability and versatility are non-negotiable, air-operated double-diaphragm (AODD) pumps excel where other technologies struggle. As an air-driven positive displacement pump, AODD pumps displace fluid at one end while suction occurs at the opposite end.

This reciprocating style differs from centrifugal pumps, which move fluid by the rotational energy created by driven rotors (impellers). The other main differentiator is the type of substances the pumps can transfer. With AODD pumps, it is possible to pump suspended solids, where this can be limited with centrifugal pumps.

And that is just the start. AODD pumps have a number of benefits, including:

  1. Easy to install. AODD pumps do not require laser alignment or other complex installation methods, nor do they require an electrical connection.
  2. Easy to operate. An AODD pump can be controlled with a simple valve.
  3. Low maintenance. AODD pump designs require only a handful of parts. Fewer parts mean fewer repairs, making the pumps easier to maintain than some other pump types.
  4. Low cost. Compared to other pumping technologies, AODD pumps typically offer a much lower price point.
  5. Rugged. AODD pumps are known for being durable and are often chosen for heavy-duty applications.
  6. Reliable. AODD pumps have few moving parts that can wear and require repairs, making them very reliable.
  7. Solutions to common pump problems. AODD pumps offer advantages that help overcome the limitations of other pump types, such as run-dry, deadhead, and solids-handling capabilities.

AODD pumps are integral in operations across many industries and sectors, particularly for sludges, abrasives, and slurries. Typical applications include:

  • Mining
  • Industrial and municipal wastewater
  • Ceramics
  • Electroplating and anodizing
  • Pulp and paper
  • Oil and gas
  • Chemical manufacturing/distribution
  • Food processing
  • Pharmaceutical
  • Coatings/paint/ink
  • Filter press

In industries where downtime is costly and conditions are demanding, AODD pumps deliver performance you can count on.
