LEWA metering system

Customer-Specific Metering Systems from LEWA

Is there a special procedure in your production process that requires a custom metering system? Then you've come to the right place: For more than 60 years, LEWA has been creating customer-specific metering systems and handling every process phase from planning and production through to installation and maintenance.

We create flow rates between 10 ml/h and 180 m3, and discharge pressures of up to 1200 bar.

Metering systems from LEWA
A custom-designed system for every application.

Metering, cooling, heating, controlling, regulating – our customer-specific metering systems ensure the interaction of the pump, instrumentation, and accessories. LEWA takes your application and specification, your interface logic, and your ideas into consideration and implements them accurately and comprehensively.

We handle all the preliminary planning, on-site data collection, and testing and calculation of the secondary systems and pressure conditions. The metering system or filling system is integrated into your new or existing plant.

LEWA metering system

Good reasons to choose a metering system from LEWA

LEWA designs and builds turnkey metering systems in closed loop control with monitoring and plausibility testing equipment for various production processes.

Experience and consulting

Years of experience for perfect metering system designs

We have many years of experience in mixing liquids of different viscosities at various temperatures and pressure levels. And we use this knowledge when creating customer-specific metering systems for companies in various industries.


Customer-specific Design

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.


Smartcontrol Controls

The control system as the intelligence center of the metering system

Precise, fast control of the metered flow in the case of changes to setpoint values or other deviations 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. Our systems are equipped with PLC interfaces to Profibus DP, CAN, MOD-Bus or Ethernet, for example.


Heart 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 metering 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.

Basic componentsAdditional components

Options

Intellidrive technology

Using the highly-dynamic servomotor, you can adjust the stroke of the pump to the requirements of your system and your process.

Different drive types

We flexibly react to environmental conditions: Pumps in our Chemical Injection Packages are driven by electric (solar energy), compressed air, gas or diesel engines.

CIP/SIP capability for pharma applications

For applications in pharmaceutical, cosmetic and food industry, we offer our pumps and systems in sanitary & hygienic design, which fulfils all standards and norms.

Customized valves

LEWA uses numerous special types of valves such as specially hardened valves for liquified gases or valves with minimal dead space for the food and pharmaceutical production.

Pipelines according to all standards

The piping of our systems can be designed according to different standards: dairy pipe, DIN, ANSI, JIS, Ermeto, Swagelok, Aminco HP, Tri-Clamp etc.

Examination by experts and authorities

We also gladly provide performance diagrams and certificates of static pressure tests also by TÜV, Germanischer Lloyd’s, Lloyd’s R. of S. or other authorities.

Global commissioning

With our global service network, we take your equipment into operation and provide technical service directly at your location - both onshore and offshore.

Complete documentation

Receive supporting documents and certificates, including the operating instructions, as well as design and test details in different languages.

Testing, acceptance and inspection

We make sure that everything works: LEWA offers numerous services, including factory acceptance test (FAT) at the manufacturing site or at your site (SAT), NDT and PMI.
