Sustainably successful since 1834

Sulzer is a global industry leader in fluid engineering with sustainable pumping, agitation, mixing, separation and application technologies. From its beginnings in Winterthur, Switzerland, back in 1834, Sulzer has developed to become a reliable, fast, and trusted partner for its customers, with a responsive network of 160 world-class manufacturing facilities and service centers across the globe.


Sulzer’s first full year under Dr. Suzanne Thoma’s leadership saw robust growth across its businesses, reflecting an operational focus on structurally growing markets and a strategic focus on operational efficiency.

With ongoing global emphasis on energy and water security, Sulzer continued pioneering new transition technologies for biofuels, decarbonization and energy storage in 2023 while also optimizing customer operations through repairs and refurbishments.

Coupled with the launch of two new biopolymer technologies and the soft launch of a clean technology R&D center in Singapore, 2023 confirmed Sulzer’s leadership in biopolymers, ensuring the company is poised to support rising demand for more eco-conscious, circular economies.


In 2022, Sulzer’s Board of Directors appointed its Chairwoman, Suzanne Thoma, as Executive President of Sulzer, in view of the constantly evolving market environment and the associated shift in demand in the energy and infrastructure sectors. 

The move was intended to enable Sulzer to realize its untapped potential in the large and growing markets of energy, environment and industrial processes – particularly in the areas of resource and energy efficiency, decarbonization, water treatment, bio-based polymers and the circular economy.  

Sulzer also published a standalone sustainability report in 2022, further demonstrating the company’s increasing focus on sustainability. Among the highlights from the report were a 25% reduction in CO2 equivalent emissions in 2021 and a five-fold increase in the adoption of decarbonized energy.

Sulzer acquired Nordic Water, a leading supplier of water treatment technology. Announced in January and closed on February 1, 2021, the acquisition strengthened Sulzer’s wastewater treatment offering and provided further access to the clean water market. Water is now the largest business in Sulzer’s Flow Equipment division, and its comprehensive portfolio of water treatment solutions mean that it provides for every stage of the water life cycle.

With this, Sulzer continued its industrial repositioning towards higher growth markets. Sulzer has now strong positions in sustainable ventures such as water treatment, energy efficiency, recycling, biomaterial applications, low carbon solutions and healthcare.

Sulzer successfully completed the spin-off of its Applicator Systems division, renamed medmix. As part of the Sulzer family, medmix became a global leader in high-precision delivery devices for markets ranging from healthcare to adhesives and beauty. Now independent and with a valuation close to CHF 2 billion, profit margins of 25% and over 900 active patents, medmix’s success and innovations touch billions of people’s lives.



In line with its strategy to complement the portfolio with bolt-on acquisitions in fast-growing markets such as medical and water, Sulzer acquired Haselmeier. The acquisition provided Sulzer access to the highly attractive drug delivery devices market. With its self-injection pens for reproductive health, diabetes or osteoporosis patients, Haselmeier is a great fit to Sulzer’s Applicator Systems division, leveraging its precision injection-molding expertise.

To effectively govern Sulzer’s sustainability agenda, the Board of Directors extended the scope of the Strategy Committee and renamed it to Strategy and Sustainability Committee. In addition to strategic matters, it advises the Board on the company’s sustainability initiatives and objectives.

Sulzer grew its aftermarket activities in July 2019 through the acquisition of Alba Power, a leading service provider for aeroderivative gas turbines. These light and compact turbines are prevalent in the distributed power segment, a market that continues to develop as power generation becomes more decentralized. By diversifying its service offering, Sulzer continued to balance its end-market exposure away from the challenging utility power sector.

Sulzer’s efforts in sustainable packaging were recognized by Packaging Europe. In the most prestigious packaging innovation competition, Sulzer’s ecopaCC™ collapsible cartridge was awarded the Sustainability Award in the “Resource Efficiencyˮ category.

Enriching its long tradition of supporting communities, the company launched the “Sulzer Scholarship for Women in Science and Engineering”, directed at female students studying for degrees in the areas of engineering, technology and science. The scholarship ultimately aims to support and increase the participation of women in the engineering industry. Reflecting its worldwide presence and specific country requirements, Sulzer awarded scholarships in China, India, Indonesia, South Africa and Brazil.
