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.
Areas of Application for Chemical Pumps
We plan, develop, and manufacture custom chemical pumps and systems for a wide variety of application areas and processes from the chemical industry. Depending on the design and configuration of our chemical pumps and systems, the following operating ranges apply:
- Viscosity: min. 0.1 mPa∙s, max. 1500000 mPa∙s
- Fluid temperature: min. -80°C, max. +200°C
- Rigid pressure characteristic curve: max. 1200 bar
