Key Benefits of Chemical Pumps and Metering Packages in the Chemical Industry

High end pumps, equipment and systems

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.

International standards

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.

Variable pump heads

We equip our pumps with application-specific pump heads, e.g. for increased safety in the processing of ethylene oxide and other hazardous substances.

Remote head design

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.

Pilot plant for process optimization

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.

Tried and tested modular system

We design our systems and units in modular design with numerous engine and pump head combinations for different applications.

Special materials

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.

Heating and cooling devices

We respond flexibly to extreme requirements: Pump heads and the complete chemical pump can be equipped with a heating or cooling device, if necessary.

Patented sandwich diaphragm

Our patented diaphragm metering pumps use metal or PTFE sandwich diaphragms with Diaphragm Protection System (DPS) for maximum operational safety.
