Sulzer completed the sale of its Metco division to Oerlikon. The division, which was mainly active in parts of the automotive, aviation, and general industries, was divested in line with Sulzer’s strategy to focus on the three key markets oil and gas, power, and water.



Sulzer focuses its activities in the three key markets oil and gas, power, and water. The key markets strategy is supported by changes in the operational structure. Sulzer Turbo Services and the service activities of Sulzer Pumps are combined in one new division for all rotating equipment services.

Sulzer Pumps wins numerous large orders for various FPSO projects, further reinforcing the division as a recognized player in the market. With the acquisition of Tartek Oy, a specialist in manufacturing mechanical seals, Sulzer Pumps further expands its technology portfolio.

Crisis and restructuring


Closure of the Oberwinterthur foundry.


Non-Swiss shareholders are permitted for the first time.


Sulzer stops production at the Winterthur factory. Its various departments are reassigned to the product divisions (“verticalization”) in an attempt to streamline the product areas. The historical Winterthur site is cleared, and work started on reutilization plans. For the first time in Sulzer’s history, the number of Sulzer employees abroad exceeds the number in Switzerland. The diesel engine business is divested to the new Sulzer diesel company, in which Sulzer holds a minor participation. 


Corporate reorganization measures lead to restructuring of the product portfolio. The medical technology business expands intensively (including acquisition of the Intermedics Group, USA). A hostile takeover bid is averted. 


Sulzer takes control of Plasma Technik AG with four facilities in Switzerland, USA, England, and Singapore. The materials and surface technology business is an excellent fit for Sulzer and in line with its research and development activities.

Sulzer’s 150th jubilee celebrations coincide with extensive restructuring activities. For the first time in many years, the corporation records a net loss and does not pay out a dividend to its stockholders. 


Sulzer acquires the Rüti machine factory; a strong expansion of the weaving-machinery business follows. 

1970 onwards

The oil crisis of the 1970s leads to an end of the economic boom which had lasted for about twenty five years. The strong Swiss franc has a negative effect on Sulzer’s exports. To master the resulting difficulties, the Sulzer Corporation is reorganized into a presidential system with responsibilities on a decentralized basis. 



Sulzer establishes a corporate structure, whereby the four-member corporate executive management assumes overall business responsibility according to the collective responsibility principle.

Material technology activities are intensified and form the basis for medical technology products. The fundamental change from a machine-building company to a technology corporation starts to become apparent.


Sulzer acquires a 53 percent share in Escher Wyss AG, Zurich, and takes over the company completely in 1969. As a result of this integration, employee figures rise to more than thirty thousand. 


Sulzer acquires the Swiss Locomotive and Machine Factory (SLM), Winterthur.

Beginning of the boom in the large diesel-engine business.

1945 onwards

After the Second World War, a new growth phase starts that brings great prosperity and strong expansion of business activities abroad. In order to meet steadily rising production demands, increasing numbers of employees are recruited, especially from southern Europe. 

Due to ongoing construction activities at the Oberwinterthur site, manufacturing facilities are tripled within twenty-five years. The product range expands, particularly in the boiler-construction and textile machinery.

Construction of housing increases steadily in Winterthur suburbs and surrounding regions.

Employees benefit from better working conditions and social welfare. Female labor is promoted for light factory work.

The crisis of the 1930s 


With the rise of political totalitarianism in Europe and after a narrowly avoided strike at Sulzer, an industrial peace agreement is signed. Employers and employees of the Swiss machine industry thereby agree to negotiate in good faith instead of taking militant action.

1930 to 1937

Due to the global slump, production declines to less than 40 percent and many employees lose their jobs.

Foundation and growth 


Sulzer initiates Switzerland’s first regularly published in-house magazine. At the same time, the technical customer magazine “Technische Rundschau Sulzer” (today “Sulzer Technical Review”) is launched.

The family firm is transformed into three joint-stock companies, one of which is the holding company.


Sulzer starts to build compressors.


Cooperation with Rudolf Diesel leads to the development of the first Sulzer diesel engine. This engine gradually replaces the then-dominant steam engine.

The first workers’ council in Switzerland is founded. 


Sulzer opens a subsidiary in Ludwigshafen on the Rhine (Germany). It flourishes, as does the parent company in Winterthur.

During the years following, sales offices are opened in Milan, Paris, Cairo, London, Moscow, Bucharest, and, in 1914, in Kobe (Japan).


A new growth period begins: Sulzer experiences international success especially with steam engines. Employee figures continued to rise, reaching three thousand by the turn of the century.

Sulzer starts to build refrigerating machines.


During the initial phase of Winterthur’s first large-scale social housing plan, twenty-four low-cost employee rental apartments are constructed in Veltheim, Winterthur. The “Society for Affordable Housing Construction” soon adds further apartment buildings and the first private homes for employees in other parts of Winterthur. (In 1989, the city of Winterthur receives the Wakker Prize—an award for cultural heritage—for its outstandingly maintained employee housing estates). 


To ensure an adequate supply of qualified young craftsmen, Sulzer opens the first in-house training school in Switzerland, including an apprentice workshop. 


Sulzer enjoys great successes at the World Exhibition in Paris and six years later in Vienna. 

For the first time in its history, Sulzer employs over one thousand workers.

Extensive building activities are carried out at the original site in Winterthur.

Around 1860

The first sales office abroad is opened in Turin, Italy. 


The first trading-company agreement between the Sulzer brothers is made, whereby company activities are divided into divisions. Entrepreneurial thinking and the willingness to take a risk lead to the introduction of new products (such as steam engines and, later, steamboats) with more efficient industrial production methods.

The English design engineer Charles Brown joins Sulzer. With the development of groundbreaking new steam engines—the first Sulzer steam engine left the workshop in 1854—he is instrumental for the early successes and the growth of the company. Charles Brown’s expertise as an inventor and engineer and Johann Jakob Sulzer-Hirzel’s talents as an entrepreneur and salesman proved a winning combination over a period of two decades.


A “Sickness-Benefit Association for Factory Workers” is founded. This is the first step towards a health insurance plan for the company. 


The first Sulzer steam engine installed in Winterthur creates a sensation.

A new foundry is constructed, and the original building becomes a machine shop. 


Still largely a workshop establishment, the business then employs forty journeymen, laborers, and apprentices, some of whom receive room and board with the family. Though patriarchal in accordance with the times, the company takes the first stepstowards a division of labor. 


Through an exchange with the city of Winterthur, Johann Jakob Sulzer-Neuffert acquires a 5000 m2 site on Zürcherstrasse, and lays the foundation stone of “Sulzer Brothers Foundry, Winterthur”, known today as “the 1834 building”. His two sons, Johann Jakob and Salomon, start producing cast iron. They also manufacture firefighting and other pumps as well as textile machinery and later set up a heating installation business. 

The credo of the first Sulzer patron was: “Whatever you do, do it right. It will not cost you more time to do it well than to do it badly.” Jakob Sulzer (1782-1853)
