1" Cognito EODD Pump
Long Lasting and Efficient
The 1” Cognito Electric–Operated Double Diaphragm (EODD) Pump was thoughtfully engineered for continuous duty applications. Designed to deliver viscous fluids like ink, glue starch, and latex safely and reliably at pressures up to 116 PSI (8 Bar). Its small footprint makes it ideal for OEM applications like hot glycol circulation in the oil and gas industry or for dispensing vehicle maintenance fluids (oil, anti-freeze, and windshield solvent) for commercial, mining, and industrial applications. The patented pump diaphragm design and virtually maintenance-free drive mechanism ensure an extended MTBF. Cognito EODD pumps deliver the attributes of an AODD pump with the enhanced efficiency, longevity, and control of electric.

Performance Curve
- Use 2 hp / 1.5 kW motor for above 2.5 amps
- The Performance curve is based on the following: Santoprene Elastomer fitted Pump, flooded suction, water at ambient condition 25°C, with Cognito Dampener
- The performance result may deviate in excess of 5% based on the elastomer
- Performance varies based on viscosity
- NPSH-R curve @6bar Max. discharge condition
