    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.

  • Historic milestone 1954, rocker arm pump

    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.

  • Historical milestone 1955, First Achema

    First ACHEMA | 1955

    First ACHEMA | 1955

    The very first modest fair participation was a great success!

  • Historic milestone 1985, Odorizing system

    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.

  • Historic milestone 2003, LEWA ecoflow

    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.

  • Historic milestone 2004, Worlds biggest process pump

    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.

  • Historic milestone 2005, DBAG

    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.

  • Historic milestone 2009, LEWA intellidrive

    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).

  • Historic milestone 2009, Nikkiso

    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 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.
