LEWA

LEWA is a German industrial pump and process-systems manufacturer headquartered in Leonberg, in the Stuttgart metropolitan region. The company develops diaphragm metering pumps, process diaphragm pumps, customized metering and mixing systems, odorizing systems, and production units for applications where accurate, reliable, and controlled fluid handling is required. Its customers operate across oil and gas, chemical and petrochemical processing, plastics, power and energy utilities, pharmaceuticals, biotechnology, personal care, and cleaning and detergent production. The business began in 1952 as Ingenieurbüro LEWA, an engineering office established by Herbert Ott and Rudolf Schestag. The name LEWA is derived from Leonberger Wasseraufbereitung, referring to water conditioning in Leonberg. In its early years, the company concentrated on engineering and pump technology. A 1954 patent application for a rocker arm pump and the company’s first participation in the Achema industrial exhibition in Frankfurt in 1955 marked early steps toward commercial and technical visibility. Research and development became more formalized in 1961, when LEWA established a research group. The company later applied for a patent covering a sandwich diaphragm for diaphragm pumps in 1968. From 1971 onward, LEWA expanded beyond individual pump technology and began developing complete metering systems and production units. This shift laid the foundation for its later positioning as an engineered-solution provider rather than solely a component manufacturer. A major product development was the introduction of the LEWA ecoflow diaphragm pump in 2003. The ecoflow became an important contributor to the company’s business and represented the continuing development of LEWA’s controlled, low-leakage pumping technology. In 2011, LEWA also developed a system for process chromatography, extending its application range into a specialized process industry field. LEWA’s ownership changed during the 2000s and 2010s. Deutsche Beteiligungs AG acquired the company in 2006. Since 2009, LEWA was part of the Japanese Nikkiso group, whose wider activities included industrial and specialized pump-related businesses as well as equipment for water conditioning, aerospace, and medical applications. LEWA’s management structure changed several times during this period. Bernd M. Stütz handed over the chief executive position to Naota Shikano in 2013. In 2016, Peter Wagner became managing director and assumed leadership of a newly created industrial division that included LEWA and other Nikkiso-related businesses. In 2018, Tsunehisa Suita replaced Wagner at the head of the LEWA Group. Since 2022, LEWA has been part of the Swedish Atlas Copco Group. Within that broader industrial portfolio, LEWA continues to operate as a specialist provider of metering, process-pumping, and customized fluid-handling solutions. Its systems are used in demanding industrial environments, including oil and gas and chemical production, where pressure capability, dosing precision, containment, and system integration are important purchasing criteria. Publicly available reference material identifies products with discharge pressures reaching up to 1,200 bar, including the ecoflow, ecosmart, and ecodos metering-pump families and the ecoflow and triplex process-pump offerings.

LEWA was founded in 1952 in Leonberg, Germany, as Ingenieurbüro LEWA by engineers Herbert Ott and Rudolf Schestag. The name originated from Leonberger Wasseraufbereitung, or water conditioning in Leonberg. The company initially operated as an engineering and pump-technology business, developing equipment for controlled fluid handling. Its early technical development included a 1954 patent application for a rocker arm pump. In 1955, LEWA appeared at Achema in Frankfurt for the first time, giving the young company a presence at one of Germany’s important industrial and process-technology exhibitions. In 1961, it established a dedicated research group to advance pump development. LEWA applied for a patent for a sandwich diaphragm used in diaphragm pumps in 1968, an innovation associated with the company’s continuing focus on diaphragm technology. Beginning in 1971, LEWA expanded its scope to include complete metering systems and production units. This broadened the company’s role from pump supplier to systems engineer. Its technology became relevant to industries requiring accurate dosing and reliable containment, including chemical processing, energy, oil and gas, and later pharmaceutical and biotechnology applications. The launch of the LEWA ecoflow diaphragm pump in 2003 was a significant product milestone and became an important support for the company’s revenues. In 2006, Deutsche Beteiligungs AG acquired LEWA. The company’s long period as a family-owned business had already ended with the death of Herbert Ott in 1999. In 2009, LEWA became part of Nikkiso, a Japanese industrial group with activities in pumps, water conditioning, aerospace equipment, and medical technology. LEWA continued broadening its engineering capabilities during the Nikkiso period. In 2011, it developed a system for process chromatography. Management changes followed in 2013, 2016, and 2018. Bernd M. Stütz handed the chief executive role to Naota Shikano in 2013. Peter Wagner became managing director in 2016 and also led a newly established Industrial Division comprising LEWA and several other Nikkiso-related businesses. In 2018, Tsunehisa Suita replaced Wagner as head of the LEWA Group, while Wagner moved to the leadership of Nikkiso’s Cryogenic Industries group. Since 2022, LEWA has belonged to Atlas Copco Group. The company remains headquartered in Leonberg and continues to supply diaphragm metering pumps, process pumps, and integrated systems. Its current product scope includes metering pumps such as ecoflow, ecosmart, and ecodos; process-pump products including ecoflow and triplex; and customized metering, mixing, odorizing, and production systems. Reference material describes applications across oil and gas, chemical and petrochemical production, plastics, energy utilities, pharmaceuticals, biotechnology, personal care, and cleaning and detergent manufacturing, with some products specified for discharge pressures of up to 1,200 bar.
