Since 1946 Klaus Union is a market leader in the development of pumps and valves that meet the most exacting quality requirements. And this is as it should be, since our products are used to transport aggressive, toxic and explosive substances in the chemical and petrochemical industries.  We play a major role in ensuring that plants in these industries operate reliably and in a manor that protects both people and the environment.

Safety and environmental protection

Magnetic drive/magnetic coupling technology offers distinct long and short term advantages over conventional sealing systems on extreme and hazardous process applications. This technology does away with the need for shafts to pass from liquid to non-liquid environments which means that glands and face seals can be dispensed with. The liquid is hermetically sealed in a leakproof, static isolation shell.

Guaranteed quality

Advanced design engineering and latest-generation technologies can only provide optimal safety if the requisite quality assurance measures are taken during the manufacturing process. Therefore a quality assurance system that encompasses the entirety of the product lifecycle is an integral part of our company policy.

Product portfolio

Our product portfolio comprises pumps and valves for virtually all industrial applications. In addition to steel and stainless steel, our products integrate numerous corrosion-proof alloys based on Ni-Cr-Fe, Ni-Cr-Fe-Mo, nickel and titanium.

Our pumps and valves offer optimal safety and reliability, as well as a long service life, and reduce costs thanks to their maintenance friendliness for the following application scenarios: chemical and petrochemical industry; refrigeration and heat engineering; liquid gas plants; electroplating; power plants; and plant construction.
