Lightnin at 100: A Century of Innovation in Industrial Mixing Technology
For more than a century, Lightnin has helped shape the future of industrial mixing technology. From wastewater treatment and pharmaceuticals to food processing and mining, Lightnin mixers have become synonymous with reliability, efficiency, and engineering innovation.
As the brand celebrates 100 years of mixing excellence, the milestone highlights not only a long history of product innovation, but also the evolution of industrial processing itself.
Come back in time with us and recap the rich history of this legacy mixing brand.
The History of Lightnin: 100 Years of Industrial Mixing Leadership
It all started with MIXCO in 1923, a small, New York-based mixing equipment company that named its primary mixer brand, Lightnin for its quick turnaround time. From there, a series of influential thought-leaders joined the company, including Dr. Henry Rushton and Dr. James Oldshue, both notable contributors to the industrial mixing industry. With them came cutting-edge technologies, like the invention of the flat-bladed radial turbine and the continuous mixing column.
The MIXCO company moved its headquarters to Rochester, NY in the late 1920s. And from there, the company’s founders quickly created deep ties with the local community including a long-standing relationship with the Rochester Institute of Technology that to this day, continues to recruit world class engineers to the Mixing Solutions team. Their deep passion for the technology of mixing has built an engineering powerhouse at the base of all we do.
Over the period of 1950 – 1990, the Lightnin founders drove a strategy to globalize the famous brand – beginning with our Poynton office in the United Kingdom and finally our Shanghai, China office in 1990. The reliability of the Lightnin brand globally was a key driver in its ability to scale globally.
By the late 1970s, MIXCO had undergone several acquisitions to become a brand within a new company named General Signal. It was here that the Lightnin 70 series gearbox was invented. The first of its kind, the Lightnin 70 series gearbox was and is ideal for heavy-duty mixing applications like mining in harsh environments.
Since then, the brand was acquired by SPX Corporation and now with SPX FLOW, continues a legacy of groundbreaking industrial mixing innovations.
Some of the most significant milestones in Lightnin’s history include:
- Development of the flat-bladed radial turbine, a major advancement in mixing technology
- Introduction of the continuous mixing column
- Launch of the A310 hydrofoil impeller in 1981, which became an industry standard for hydrofoil impellers
- Adoption of advanced computer modeling and LDV validation systems for impeller development
- Rapid delivery of mixers during the COVID-19 pandemic to support pharmaceutical vaccine production efforts
Today, Lightnin continues to serve customers across more than 140 countries through SPX FLOW’s global mixing solutions network.

A Legacy Built on Mixing Innovation
One reason Lightnin has remained a leader for over 100 years is its continued investment in research and development.
SPX FLOW’s Innovation and Design Centers support customers with process testing, computational fluid dynamics (CFD), pilot-scale validation, and advanced mixing analysis. These capabilities help manufacturers improve production efficiency, reduce energy consumption, and optimize mixing performance before scaling operations.
The company was also among the first in the industry to use CFD modeling in mixer development, enabling engineers to improve fluid flow patterns, reduce operating costs, and increase process reliability.
This focus on innovation has resulted in technologies that continue to perform for decades in the field. SPX FLOW recently highlighted examples of Lightnin mixers still operating after more than 70 years of service.
Lightnin Reliability and Long-Term Performance
In industrial processing, unplanned downtime can significantly impact productivity and profitability. Lightnin’s engineering philosophy has long emphasized durability, serviceability, and low total cost of ownership.
The company’s proprietary gearbox technologies, hollow quill drive systems, and anti-fouling designs are engineered to withstand challenging process conditions while extending equipment lifespan.
In addition to equipment manufacturing, SPX FLOW supports customers through:
- Predictive and preventative maintenance programs
- Gearbox exchange services
- OEM replacement parts
- Mixer repair and refurbishment services
- Global aftermarket support networks
This comprehensive support model helps customers maximize uptime while reducing maintenance costs and operational risk.
The Future of Industrial Mixing Technology
As manufacturing industries continue evolving toward sustainability, efficiency, and digital process optimization, mixing technologies must evolve as well.
Lightnin continues investing in advanced impeller designs, energy-efficient systems, and process optimization technologies that help customers improve operational performance while reducing environmental impact.
The integration of brands including Lightnin, Plenty, Stelzer, Uutechnic, and Philadelphia Mixing Solutions has also expanded SPX FLOW’s ability to provide specialized mixing expertise globally.
According to SPX FLOW leadership, the company’s mixing brands collectively represent more than 300 years of industry experience.
