Grease and oil metering
Dispensing systems for the clean and precise application of lubricants
There are over 200 regular greasing and oiling applications involved in the production of a vehicle. Depending on the model, this can also be a lot higher. These applications ensure smooth operation, reduced friction, durability and noise prevention. Greasing and oiling applications play a similar role in furniture production. The application of lubricant on door hinges or drawer runners enables the doors and drawers to be opened and closed smoothly.
The requirements for each of these applications are different, and many factors need to be taken into account in the system design. Should the application be carried out in dot, bead or spray form? In what timeframe should the application be carried out? How is the metering system integrated into the production line? Key factors such as material properties or temperature play an important role in system design. There are special greases that are only used in wet environments, for example, and others that were specially developed for extreme temperatures. The valve and material should be perfectly coordinated.
The system concept generally comprises three main components: material feed, metering and dispensing valves, and process monitoring systems. DOPAG developed the lubriLine product line specially for the application of lubricants. All components can be used in a modular way and combined to form an individual system concept. Different drum and barrel pumps, pressure tanks and a transfer pump are available for the material feed. Depending on the requirement, there can be different system designs, such as a multi-part metering unit with a dispensing valve or a system with a metering valve. Various measuring devices can be added to ensure reliable process monitoring and reproducibility, such as a light barrier, a gear flow rate measuring cell or a pressure sensor. In this way, the system concept also be optimally integrated into fully automated production lines.
We configured an automated lubricant dispensing system that optimises production processes in the automotive industry.
The contactless application of lubricants meets all conditions for complex, automated production processes and is now standard in many industries. We present the options.
DOPAG offers special dispensing stations for the manual application of lubricants. With the help of an adapter, components such as O-rings and other seals can be greased or oiled manually.
DOPAG offers furniture manufacturers flexible and reliable solutions for the automated application of lubricants.
- Valves for the spray application of grease and oil. Contactless application of lubricants in areas difficult to access.
The requirements for the type of lubricant dispensing vary and always depend on the application being carried out. Learn here more about the four key factors for successful system design!
The membrane dispensing valve ensures a clean application and a high reliability in automated dosing processes.
DOPAG presents the shot valve in a new video: It is perfectly suited for contactless material application in highly automated processes.

Individual consulting and project support
In DOPAG’s competence centre in Cham (Switzerland), experts are constantly working on the further development of metering components and pumps.
During the project phase, DOPAG customers receive comprehensive consultation, from feasibility studies, initial design and tests in their own technical centre to on-site commissioning.
The end result is reliable, precise metering systems that meet all the requirements for automated production processes with their high quality standards.
For maximum precision and reliability:
- Precise, stable production processes thanks to decades of experience in designing metering and application systems for greases and oils
- Reliable process monitoring and reproducibility through precise measuring devices: light barriers, flow measuring cells, pressure sensors, etc.
For specific solutions that meet all the relevant requirements:
- Application in the form of dot, bead or spray application
- Application in exact cycles or time units
- Consideration of all key factors including material properties or temperature
- Integration of metering system into production line
For cost-efficient solutions:
- Long service life of all components
- Efficient production through material savings, e.g. low residual quantities in the drum
- Rapid availability of replacement parts
Individual configuration of drum and pumps
Thanks to the modular design of DOPAG drum pumps, customers can combine various modules and features to create a product that perfectly matches their needs. With the DOPAG pump configurator, you could configure the right pump for your application just with a few clicks and request a quotation directly. All you need to know to use the tool are the material properties, drum/container dimensions and the features you want your new pump to have.
In addition to the standard version, you can add certain options depending on your requirements. These include a material filter, mixer, connecting block and pressure release. Depending on the container size, a drum roll-in mechanism can also be selected for convenient drum changing. If you have any questions, our experts will of course be happy to advise you at any time.
