Specialist for piston diaphragm pumps for 70 years
Josef Emmerich founded his company of the same name in Cologne in 1945, which today exists as an independent, medium-sized company based in Hönningen-Liers. 70 years of experience have made Emmerich one of the leading specialists for conveying abrasive suspensions in the high-pressure range.
The company focuses on piston diaphragm pumps with decades of in-house diaphragm production. As a result, it has mastered the entire production chain, from design to production and sales, and impresses with a mixture of tradition and innovation.
From 1945, company founder Josef Emmerich assembled small hand and centrifugal pumps in Cologne-Bayenthal with just a few employees, mainly for agricultural businesses. For the first ten to fifteen years, these were exclusively pumps in the low-pressure range. As early as the 1950s, his pumps reached as far as Taiwan and Canada with the help of a sales partner.
Emmerich GmbH has been manufacturing molded rubber parts and rubber-metal compounds in-house since 1975.
In 1995, Emmerich GmbH was the first company to develop a pump with a pump head made of polypropylene for large volume flows, an operating pressure of up to 16 bar and a temperature of up to 80°C.
