April 17, 2025

Warren Rupp is revolutionizing the fluid transfer industry with its brand Cognito, the electrically operated double diaphragm (EODD) heavy-duty pump. The team recently introduced a new 1-inch model to their Cognito line of pumps. This 1-inch model is a measure of the intake and discharge pipe diameter, indicating the size of the inlet and outlet pipe.

Cognito pumps are designed to be highly energy-efficient, reliable, and sustainable. Unlike traditional pumps that rely on compressors and consume more energy, Cognito uses an advanced electric drive, saving up to 70% more energy. This innovation not only reduces energy consumption but also lowers the carbon footprint, making it a game-changer in the industry.

“Designed with our customers in mind, Cognito pumps provide innovative, energy-efficient options to move viscous fluids,” said David Llewellyn, General Manager at Warren Rupp.

Archana Gundre, Managing Director, FMT Pumps Group – Asia, added, “We are thrilled to introduce the Cognito 1” pump, marking the completion of our heavy-duty EODD range. Engineered for energy and operational efficiency, this pump is equipped with the same revolutionary features that have been establishing Cognito as a benchmark in various industries.”

This 1” heavy-duty pump, available in SS, AL, and PP materials, is specifically designed for core market segments like Oil & Gas, Chemical, Paints and Coating, Pharma, LI Battery, and PCB. The pump is best suited for unloading applications, including barrel, drum, OBC, and underground tank/pit unloading, where flow rates required are in the range of 100-110 LPM, and space is compact.

Key features of the new Cognito 1″ pump include:

– Energy Efficiency: It saves up to 70% in energy compared to traditional pumps, reducing environmental impact.

– High Performance: It offers impressive flow rates and pressure options.

– Low Maintenance: It boasts a low cost of ownership and requires minimal upkeep.

– Robust Design: It is built to last, with a longer diaphragm life and no seals, reducing failure rates.

Currently, Cognito 1” pumps are manufactured in India and China. With the introduction of the new 1-inch model, the Cognito lineup now includes a full range of pump sizes: 25 mm (1″), 50 mm (2”), 76 mm (3”), and 101 mm (4”).
