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.
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:
|Scale||Chemical base products||Chemical intermediate and end products|
| || || || |
We deliver high-end pumps integrated into complete systems and units for your specific applications. In doing so, we of course rely on the tried-and-tested LEWA quality.
LEWA pumps, systems and units are compliant with major international standards such as DVGW G280, WHG, PED, ISO 9001, ASME, ATEX and TA-Luft. Of course, you can also define your own standards.
We equip our pumps with application-specific pump heads, e.g. for increased safety in the processing of ethylene oxide and other hazardous substances.
For extreme applications, we offer low and high temperature pumps in remote head design. Thus, we protect the sensitive parts of the pump for a longer lifetime.
You can rely on over 60 years of experience in the design of equipment and systems: In cooperation with you, we develop pilot plants to optimize your processes and procedures.
We design our systems and units in modular design with numerous engine and pump head combinations for different applications.
On request, we can build systems with special materials such as Hastelloy, titanium, duplex stainless steel or further materials. If you are interested, please contact our product manager.
We respond flexibly to extreme requirements: Pump heads and the complete chemical pump can be equipped with a heating or cooling device, if necessary.
Our patented diaphragm metering pumps use metal or PTFE sandwich diaphragms with Diaphragm Protection System (DPS) for maximum operational safety.
