Our LEWA ecofoam system provides a tested and modular metering system for your specific application in the field of physically foaming polyolefins such as polyethylene processing.
This system is used worldwide by leading manufacturers and is characterized by controlled and exact metering. Not only does this ensure that the foamed product is always of a consistently high quality, it also significantly reduces scrap.
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.
High variability in operation in terms of pressure, temperature, flow rate and fluid properties with high metering accuracy guarantee a wide range of applications.
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.
An especially important advantage for pharmaceutical and food industry is that our systems can be quickly and easily cleaned with cleaning chemicals or hot steam.
Safety comes first: LEWA supplies systems and units, also available with explosion-proof motors for safety of your employees.
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.
