Chemical Pumps and Metering Packages for the Chemical Industry

When critical, environmentally hazardous, toxic, or flammable fluids and suspensions need to be reliably conveyed or metered in high-pressure processes, there is no alternative to hermetically sealed metering pumps, process diaphragm pumps, and metering systems from LEWA.

We deliver high-quality chemical pumps and custom-built systems for such applications all over the world. And you get this complete service from a single source: from consultation through to commissioning.

Chemical industry

LEWA is the Number One for Critical Procedures and Processes

In the chemical industry, systems and chemical pumps for critical processes need to be safe and reliable. Fluids in these processes are not only often extremely expensive, but also highly toxic, and bad for the environment.

That's why hermetically sealed LEWA chemical pumps for up to 1200 bar are the first choice with almost all manufacturers for the production of chemical intermediate and end products. You can rely on our tried-and-tested products and our many years of industry experience and expertise.
