Frequently Asked Questions

What is an EODD pump and how is it different from an AODD pump?

An EODD (Electrically Operated Double Diaphragm) pump uses an electric motor instead of compressed air to drive the diaphragms. This eliminates the need for a compressed air supply, delivers up to 75% energy savings, provides consistent flow rates, and offers IoT monitoring capability — advantages not possible with traditional AODD pumps.

The Cognito 50mm (2") Metallic EODD Pump uses a 5 HP / 3.7 KW electric motor for operations above 4 AMPS. The motor can be mounted horizontally or vertically depending on installation requirements.

Yes, the Cognito 50mm Metallic EODD Pump is run-dry capable. The sealless double diaphragm design means the pump can operate without fluid for extended periods without damage.

The Cognito 50mm Metallic EODD Pump delivers a maximum discharge pressure of 6 Bar, suitable for a wide range of industrial fluid transfer applications.

Yes, all Cognito EODD pumps are compatible with the Cognito Smart Insights IoT platform, which provides 24/7 real-time condition monitoring, remote health tracking, preventive maintenance alerts, and actionable insights from equipment data.
