When it comes to transferring viscous, abrasive, or shear-sensitive fluids, pump size shouldn't limit performance. That’s why Cognito is proud to introduce its new 1″ Electric-Operated Double Diaphragm (EODD) Pump — a compact yet powerful solution built for continuous-duty operation in demanding environments.
This thoughtfully engineered pump is designed to safely and reliably handle fluids like ink, glue, starch, latex, and glycol under strenuous industrial conditions. As long as your operating location has access to electricity, the 1″ EODD can deliver exceptional, energy-efficient pumping that lowers maintenance costs and downtime.
What Cognito’s New 1″ EODD Pump Is Designed For
Cognito developed this pump after recognizing a critical gap in the market: the need for compact, continuous-duty pumping solutions that don’t compromise on performance. By introducing the 1″ EODD pump, Cognito is enabling organizations to integrate high-performance pumping into smaller systems, tighter installations, and more specialized applications — without sacrificing flow rate, durability, or safety.
At its core, this pump is engineered to transfer viscous, abrasive, and shear-sensitive fluids reliably. With a patented diaphragm design, robust construction, and virtually maintenance-free drive mechanism, the 1″ EODD is ideal for applications where precision and endurance are non-negotiable.

Why Cognito Pumps Lead the Way
Cognito is at the forefront of pump innovation, delivering rugged, smart, and sustainable equipment to help customers operate with greater efficiency, safety, and reliability.
At the heart of Cognito’s product engineering is a clear goal: merge the performance of AODD pumps with the precision, energy efficiency, and control of electric operation. The result is a line of electrically operated double-diaphragm (EODD) pumps that perform under various demanding conditions.
With the launch of the new 1″ Electric-Operated Double Diaphragm (EODD) Pump, Cognito is extending that mission into more compact and specialized environments, giving operators a high-performance solution in places where space is limited.
It brings all the hallmarks of Cognito engineering:
Innovative Design
Cognito pumps are built to maximize uptime and extend service life, and the 1″ EODD pump is no exception.
- Patented diaphragm: Engineered for durability and optimal performance across a wide range of fluid types.
- Oversized diaphragms with reduced stroke length: Minimizes wear and extends lifespan, even in continuous-duty applications.
- Leak detection sensors: Integrated to proactively protect both equipment and personnel.
- Dual secondary static seals: Provides an added layer of protection against process fluid ingress.
- Maintenance-friendly layout: Lowers mean time to repair (MTTR) and increases mean time between failures (MTBF), ensuring smoother operation with fewer disruptions.
Utilizing Benefits of AODD Pumps & Taking It Further
Cognito’s EODD pumps are designed to offer all the operational advantages of air-operated double diaphragm (AODD) pumps — but with better efficiency, control, and lifecycle value.
- Energy savings up to 75% compared to traditional AODD models.
- Quieter performance, with sound levels kept below 80 dB — ideal for environments where noise control matters.
- Designed with safety in mind, containment chambers and leak detection protect the people, process and pump from harm.
- Lower total cost of ownership, thanks to reduced energy consumption, fewer maintenance intervals, and longer component life.
