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

Using the highly-dynamic servomotor, you can adjust the stroke of the pump to the requirements of your system and your process.
We flexibly react to environmental conditions: Pumps in our Chemical Injection Packages are driven by electric (solar energy), compressed air, gas or diesel engines.
For applications in pharmaceutical, cosmetic and food industry, we offer our pumps and systems in sanitary & hygienic design, which fulfils all standards and norms.
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.
The piping of our systems can be designed according to different standards: dairy pipe, DIN, ANSI, JIS, Ermeto, Swagelok, Aminco HP, Tri-Clamp etc.
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.
With our global service network, we take your equipment into operation and provide technical service directly at your location - both onshore and offshore.
Receive supporting documents and certificates, including the operating instructions, as well as design and test details in different languages.
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.
Thanks to our tried-and-tested modular system plus our extensive portfolio of pumps, we can create custom systems that always meet customer requirements exactly.

LEWA has been your expert in pumps and packages since the 1950s. With us, you get everything from a single source: Our custom-built packages are used all around the world for offshore crude oil and natural gas production. From China to the United Arab Emirates, strong partners rely on our expertise for crude oil exploration applications.More Details
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.More Details
Crude oil must be cleaned, separated, and converted (refined) until the final products suitable for sale are made (e.g., gas, diesel, heating oil, lubricants, propane, butane). LEWA supports you with pumps and metering systems, which are used in the refining process during chemical metering. Application with our products are distillation plants, coker, cracker, or visbreaker, for example. Ask our experts for more information!More Details
