LEWA production units

Customized production units for metering or mixing

Whether the task involves metering, mixing, separating or controlling temperature, we work with you to develop the ideal process sequence. To this end, we create the perfect metering package and mixing installation for your manufacturing process.

We create flow rates between 10 ml/h and 180 m3, and discharge pressures of up to 3500 bar.

Metering and mixing systems

Custom solutions for various applications.

For decades now, we have built customized production units and provided the associated preliminary planning, on-site data collection, as well as testing and calculation services for secondary systems and pressure conditions. Our knowledge of intelligent process management and the instrumentation and control technology required for it yield perfect results.

Even as early as the project planning stage, LEWA is at your side with the experience and expertise you need to reduce your process steps, prevent pipeline problems, save space and equipment, and design the process economically.

LEWA production units

Good reasons to choose a metering or mixing system from LEWA

LEWA designs and builds customized batch/continuous systems for various production processes.

Comprehensive service and consulting

Years of experience in mixing liquids

We have many years of experience in mixing liquids of different viscosities. We are also experts in the injection of slurries, especially where this involves various particle sizes and high settling rates.

Experts at LEWA develop customer specific complete systems

Experts in metering and injection processes

Our process expertise, which creates perfect results in metering and injection processes, is in demand across the world. We also have a wealth of experience in dealing with required dwell times, idle periods, post-mixing, and heat addition and removal for process reactions.

Intelligent and smart controls

The control system as the intelligence center of the system

Precise, fast control of the metering or mixing system when the setpoint value is changed ensures that the end product is always of top quality. This is achieved by a control system developed by LEWA, which continuously monitors the plausibility of set values and actual values.

The hermetically tight diaphragm is the core of the system

LEWA pumps are at the heart of our systems

We prefer to use our own diaphragm metering pumps manufactured in-house for our metering, mixing and filling systems. These are characterized by continuous stroke length and speed adjustment, ensuring an accurate and wide adjustment range. Pressure has virtually no influence on the metering characteristic, which makes monitoring easy and precise. What's more, high metering accuracy paired with a flow measurement and monitoring system ensures reliable and reproducible production.

Integration of third-party components

Our expertise also helps when it comes to integrating other pump types, provided that these lead to a better result based on the application, the flow rate or the composition of the pumping fluid: All components are adapted to meet your requirements perfectly.

Compliance with all international standards and norms

We clarify all national and international standards and regulations, as well as customer-specific and product-specific requirements, during the design phase. Our systems are developed in accordance with TÜV, API, and other specifications.


LEWA supplies systems that meet customer requirements perfectly. To achieve this, we use our tried-and-tested modular system with various components in line with the needs of the specific application.

Gas Odorization with LEWA Pumps and Metering Packages

Natural gas, oxygen, and nitrogen are odorless but potentially dangerous. This is why these gases are "odorized" with as strong a smelling substance as possible. For more than 40 years, LEWA has been developing systems for the odorization of gases such as natural gases, biogases, and liquefied gases. This process is enormously important, so the odorizing system has to operate precisely and reliably.
