Wherever fluids are pumped, mixed, controlled or applied, we are there. See how our solutions create value for customers and learn how we can make your pumping and mixing processes more efficient and profitable, safeguarding your production and ensuring lasting reliability.

Industries

Metals
Sulzer’s pumping and mixing solutions for the metal industry are designed for corrosive and abrasive liquids. We offer expertise e.g. for the production of aluminum, copper, nickel, zinc, and precious metals.
Mining
Whether on the surface or underground, the conditions in mines are harsh. Besides the mud, slurry, stones, and rocks, there are large volumes of water to remove in order to keep production moving. Our dewatering pumps are rugged and ready, taking on the toughest drainage and sludge removal.
Chemical processing
Our solutions for the chemical processing industry include pumping, separation and mixing, as well as services for rotating equipment and infrastructure. We offer experience in classical chemical, plastic, and pharmaceutical production as well as in processing renewable materials.
Fertilizers
Our pumps, mixers and agitators provide durability and reliability for fertilizers production as well as for corrosive and abrasive liquids and high gas content. Our specific industry experience also includes separation processes and servicing of pumps, compressors, turbines, and motors.
Pulp, paper and board
Sulzer is the world leader in innovative, reliable, and proven pumping, agitation and mixing solutions for the pulp and paper industry. Our deep process and application knowledge is based on long-term close co-operation with the producers, machinery suppliers and engineering companies.
Food and beverages
Food and beverage production relies on our pumping and mixing solutions. Special pumps and agitators have been developed for sugar, starch, and sweetener production. Separation equipment is often used in beverage manufacturing and our process technologies support purification and concentration.
Biofuels
Biofuels from renewable sources show great potential as sustainable transportation fuel. Based on our experience in demanding processes, we work with customers to develop advanced pumping, mixing, and distillation solutions for the production of biofuels, from pilot to commercial-scale installations.
Water and wastewater
Sulzer offers a broad range of pumps and related equipment for water production and transportation as well as wastewater collection and treatment for municipalities and industries. Our expertise also includes separation technologies, and services on rotating equipment.
