Cognito - Electrically powered double-diaphragm pump
Cognito electric double-diaphragm pumps are designed for the efficient, safe, and reliable transfer of challenging fluids. The pumps are engineered to minimize common operational challenges and offer high operational reliability, ease of use, and convenient maintenance.
With a smart and innovative design, a highly robust construction, and energy-efficient operation—consuming up to 75% less energy than comparable air-driven diaphragm pumps (AODD), Cognito EODD pumps are a sustainable and reliable choice for industrial and demanding applications where both performance and long service life are critical.
The pumps are available in both metal versions—SS316 and cast iron—as well as a thermoplastic version made of PP (polypropylene).
Cognito electric double-diaphragm pumps are suitable for a variety of demanding industries and applications, including:
- Ceramics
- Paint, coatings, dyes, and pigments
- Pulp, Paper, and Packaging
- Metal and Mining Industry
- Chemicals and Specialty Chemicals
- Lithium Batteries
- Oil and Gas
- Pharmaceutical industry
- Patented diaphragm with a larger diameter and shorter stroke for a longer service life.
- A hardened seat and ball stop design that significantly improves the service life of both the discharge pipe and the seat when pumping abrasive fluids.
- Secondary static seals that prevent fluid contact and protect the pump in the event of a diaphragm failure.
- Leak detectors that can communicate with PLC systems to automatically shut off the pump and protect both the pump and the process.
Cognito Non-Metallic EODD pumps are designed for demanding environments, including wastewater treatment and chemical transfer. They are suitable for commercial, industrial, and mining-related applications where corrosion resistance, operational reliability, and ease of maintenance are critical.
With patented membrane technology and virtually maintenance-free electric operation, these pumps combine the advantages of traditional AODD pumps with higher energy efficiency, a longer service life, and better control.
Available in sizes:
- 25 mm (1”)
- 38 mm (1.5 in.)
- 51 mm (2”)
- 76 mm (3”)
Cognito Metallic EODD pumps are designed for demanding industrial applications where high production capacity, operational reliability, and a low total cost of ownership are essential.
The pumps handle various types of liquids and slurries safely and efficiently. With smart technology for remote connectivity, monitoring, and analysis, you gain better control over your equipment, while energy-efficient operation and easy maintenance help reduce operating costs.
Available in sizes:
- 25 mm (1”)
- 51 mm (2”)
- 76 mm (3”)
- 101 mm (4”)
Pulsation dampeners
Reduces pulsations and helps ensure a steady flow and stable pressure in the piping system, which minimizes the risk of damage to pipes, valves, and instruments.
IoT platform
Enables remote connection, monitoring, and analysis of the equipment.
