Company Foundation | 1952

Company Foundation | 1952

Herbert Ott and Rudolf Schestag found LEWA.

The initials stand for LEonberger WAsseraufbereitung (Leonberg water treatment).

The beginning is an arduous time. First deliveries are made with a motorbike, the only company vehicle. Later, they have to sell the motorbike and need to hitchhike.

First Patent | 1954

First Patent | 1954

The rocker arm metering pump is registered as first patent.

This starts a whole series of innovations. LEWA gradually evolves into an expert for all kinds of fluids.

First ACHEMA | 1955

First ACHEMA | 1955

The very first modest fair participation was a great success!

LEWA's first participation at the processing industry trade show ACHEMA in Frankfurt. From now on LEWA exhibits its product variety every three years.

Standard Odorizing Systems | 1985

Launch of LEWA standard Odorizing Systems | 1985

LEWA intensively focusses gas odorization business. 

Technical innovations and central advantages of the LEWA standard Odorizing Systems are hermetically tight pumps with metal diaphragms, the closed control loop with odorant flowmeters and the modular customer-specific designs. In more than 30 years, we have been able to design and assemble more than 5,000 Odorizing Systems at locations all over the world. LEWA is constantly developing new solutions for gas odorization and, in addition to the OD7, OD8 and OD60-1000 standard Odorizing Systems, we also offer professionally qualified consultation and customized solutions.

LEWA ecoflow | 2003

LEWA ecoflow | 2003

LEWA presents the innovative metering diaphragm pump.

The M900 pump head with DPS is a versatile and safe solution for handling hazardous, harmful or highly viscous fluids. Due to DPS, the pump always performs within the ideal operating range. Even adverse external influences cannot affect it.

Gigantic | 2004

G4T – the biggest diaphragm process pump in the world | 2004

LEWA designs and manufactures the largest process pump in the world.

The two biggest pumps of their kind are used for CO₂ reinjection at a natural gas field in Hammerfest, Norway. CO₂ condensate is produced as a waste product in natural gas production. It is fed back under the ground with LEWA pumps. With this project, LEWA can not only meet customer-specific requirements, but also actively contributes to environmental protection.

Acquisition by DBAG | 2005

Acquisition by DBAG | 2005

The German private equity "Deutsche Beteiligungs-AG" acquires LEWA.

Until then, LEWA was family-run. At the time of the acquisition, LEWA generates an annual turnover of 92 million euros. By means of targeted investment, further development of the existing corporate culture as well as the recognition and better exploitation of market potentials, LEWA's business can be boosted during DBAG's investment. Strong growth is achieved: At the time of LEWA's acquisition by the Japanese company Nikkiso in 2009, LEWA generates an annual turnover of almost 150 million euros.

LEWA intellidrive | 2009

LEWA intellidrive | 2009


LEWA introduces the highly dynamic servomotor LEWA intellidrive.

With the product launch of LEWA intellidrive, we are able to model pump strokes according to the requirements of the respective plant or process. Thus, the stroke adjustment (which is customary for metering pumps) can be omitted. Thanks to the continuously adjustable stroke times, new tasks with special fluid kinematics can be successfully solved with our metering pumps (highly viscous fluids, chromatography, high pressure separation, pulsation minimization).

Acquisition by Nikkiso | 2009

Akquisition durch Nikkiso | 2009

In 2009, the Japanese Nikkiso Group acquires LEWA.

Nikkiso is active in the aviation and medical technology sectors, but also has a pump division and manufactures cryogenic and centrifugal canned motor pumps. LEWA and Nikkiso benefit from innovation exchange and joint development work as well as specific market accesses and expansion of the sales network. The Japanese company wants to expand in "overseas" and is committed to sustainable growth of the new LEWA-Nikkiso Group.

LEWA ecosmart | 2010

LEWA ecosmart | 2010


LEWA launches new diaphragm metering pump LEWA ecosmart.

LEWA ecosmart is an innovative, compact and multiplexable diaphragm metering pump at a smart price. These pumps are suitable for almost every fluid and for applications in various industries. They offer highest metering accuracy and safety as well as excellent efficiency. With the introduction of LEWA ecosmart, also LEWA PumpShop goes online. In our Webshop, customers are able to configure a pump suitable for their specific applications online. In addition to a faster delivery, PumpShop customers benefit from a 20% discount.

The 40 million dollar project | 2012

Record project – the 40 million dollar project | 2012

In the year of our 60th anniversary, we receive our largest order so far.

We supply 40 tailor-made offshore pump systems with a total amount of 186 pump heads to Saudi Arabia. The total order volume adds up to 40 million dollars.

Triumvirate | 2013

Triumvirate | 2013

LEWA-NIKKISO Group now led by a triumvirate.

Naota Shikano succeeding Bernd Stütz is now sharing responsibility for the pump and systems business of the entire group with Stefan Glasmeyer, who is responsible for Sales, and with Dr. Martin Fiedler, who is head of the Operations Division.

LEWA triplex G3M | 2014

LEWA triplex G3M | 2014

LEWA introduces the new triplex process diaphragm pump G3M.

The new pump is very efficient thanks to its compact monoblock design and the engine concept with a single-piece crankshaft. Compared to previous solutions, up to 30 percent of footprint and weight can be saved. This makes the G3M particularly suitable for applications in which space and weight play a decisive role, such as on offshore platforms.

Largest CIP | 2015

Another record-breaking project – largest Chemical Injection Package | 2015

In 2015, we completed our largest package so far.

The LEWA Chemical Injection Package is used on a Brazilian Floating Production Storage and Offloading Unit (FPSO). It weighs 715 tons and measures 21.3 x 21 x 11 meters. The ambitious project presented great challenges for our engineers. The LEWA giant was realized in more than 7,500 engineering hours. 40 diaphragm pumps, 40 IRCDs, 18 storage tanks as well as more than 3,000 instruments, valves and more than 3,500 meters of piping and tubing were installed.

New Industrial Division | 2016

New Industrial Division | 2016

In 2016, the LEWA-Nikkiso Industrial Division is formed – led by a new management team.

Peter Wagner, as CEO, is sharing responsibility with Dr. Martin Fiedler, who is head of the Operations Division, with Hisanao Amino, as Chief Financial Officer and with Stefan Glasmeyer, who is responsible for sales. The team leads the whole pump and system business of the entire LEWA-NIKKISO Group.  LEWA-Nikkiso Industrial Division is led from LEWA headquarters in Leonberg.

Expansion | 2016

Expansion | 2016

New workshops are built at LEWA headquarters in Leonberg.

The construction of a new factory building, including high-bay storage and adjacent offices, will facilitate a transition to continuous-flow manufacturing resulting in increased production capacity.
