Complete dosing systems and dosing devices
Supply: pumps and grease handling
When supplying dosing valves with lubricants or oils, it is important that they are robust in continuous operation, simple to use and easy to connect to higher-level control systems. SOMA supports you with all your requirements for a modern lubricant supply.
Lubricant supply
You want to provide your dosing valves with a continual supply of lubricant without interruptions and bubbles? We offer proven production technology for industrial grease dosing and for an optimal lubricant supply: medium pump, grease handling system and pressure balance system in industrial quality
Dosing: dosing valves
Different greasing methods are used when dosing industrial greases: e.g. volumetric dosing, contactless greasing, greasing with lubricant film or greasing for rotationally symmetrical housings. SOMA offers the right valve for you.

Monitoring: dosing processes
For demanding dosing tasks, the logical step to digitalize lubricant dosing involves seamlessly monitoring all dosing processes and providing production data directly to ERP systems. SOMA gives you full control over all the parameters of each individual grease dosing process.
Checking dosing processes
Your production has to meet the highest quality standards? If every production step needs to be transparently monitored and documented, a dosing inspection system always gives you full control over all dosing processes.

Solutions for an optimal lubricant supply
In dosing systems for industrial applications, the lubricant supply is essential and represents the first step towards an optimal dosing process. Grease supply options that are useful in industrial applications:
Grease handling systems: greasing and grease supply in production using grease cartridges
grease handling systems consist of exchangeable grease storage canisters, a central loading station and any number of local unloading stations. Therefore, they form a supply concept with numerous logistical and technical advantages and an economical alternative to a conventional grease supply from dosing devices.
Advantages of grease handling systems
- Local storage and replacement of grease containers
- Compact unloading stations replace barrel pumps in the production environment
- Short supply chain with low pressure that is gentle on the medium
- No air enters the lubricant syste
- Constant grease supply to the dosing valves
- No interruptions to production due to container changes
- Clean production environment without grease transfer
- Automatic venting in uncoupled state
Pressure balance systems: prevent pressure fluctuations when supplying industrial greases
Pressure balance systems limit the high delivery pressure in supply systems for industrial greases and highly viscous liquids before they are fed into dosing devices. They also prevent pressure fluctuations, meaning that they ensure a grease supply without fluctuating pressures.
Advantages of pressure balance systems
- Reduce system pressure and balance pressure fluctuations in one device
- Expansion tank with sensor
- Interfaces with the higher-level control system
- Continuous lubricant supply
- Even more safety with an optional digital pressure monitor
Reliably supplying greasing systems with large containers
Medium pumps are used wherever the strictest reliability and safety requirements arise in production when supplying greases, lubricants or oils. Medium pumps can be integrated into existing production environments and offer an efficient way of using customary grease containers in a straightforward manner without needing to decant.
Advantages of medium pumps
- Intelligent pressure relief when supplying lubricant
- Occupational safety: integrated safety PLC for safe two-hand operation in accordance with the Machinery Directive
- Low transmission ratios for supplying lubricant while treating the material well
- Automatic air evacuation under the follower plate
- Minimised material loss when approaching containers
- Communication interfaces with higher-level controls (e.g. PLC)
- CE-compliant operation possible even without enclosure

Solutions for automatic and contactless greasing with dosing valves
In automatic grease dosing, industrial production has very diverse requirements in terms of dosing valves. We show you which valves are suitable for which purpose.
Contactless dosing: grease complex geometries with lubricant using a contactless and volumetric concept
Whenever it is difficult to reach the area to be lubricated for geometric reasons, impulse dosing valves prove beneficial. Contactless lubricant dosing eliminates the need for additional movements in the system. Volumetric dosing ensures that the lubricant and grease are dosed reliably and with repeat accuracy in production.
Advantages of impulse dosing valves
- Contactless dosing method for technical lubricants
- Can be used in automated handling systems thanks to compact design and suitability for different positions
- High process and repeat accuracy thanks to volume principle
- Low upstream pressure to avoid lubricant segregation
- High dosing speed up to 20 Hz
- Complete monitoring in combination with dosing inspection systems
Dose industrial greases and lubricants at a high, constant volume
Volumetric dosing systems or volume dosing valves come into their own where greasing tools or contact applications are used in production. With dosing volumes of up to 235 mm³, they also supply large-volume greasing systems with lubricant with repeat accuracy and precision. Therefore, volumetric dosing systems excel in the production process with their high accuracy and repeatability.
Advantages of volume dosing valves
- Grease dosing and volumetric dosing with continuously adjustable and reproducible dosing volumes
- Volumetric dosing with low medium upstream pressure to avoid lubricant segregation when dosing grease
- Volumetric dosing systems can be combined with greasing tools in automated production plants
- Monitored material outlet for more safety when dosing
Rotationally symmetrical dosing: grease cylindrical and circular objects with precise angles and without contact
Sometimes it is not possible to lift out a component and turn it in front of the nozzle because of the cycle time and design factors. Based on hollow shaft stepping motors, any number of dosing points can be freely programmed across 360° in rotary dosing valves. Greasing is also possible from the inside and outside.
Advantages of rotary dosing systems
- Volumetric dosing systems with continuously adjustable and reproducibly constant dosing volume
- Contactless lubricant and grease dosing with precise angles
- Process reliability thanks to integrated dosing piston stroke request
- Valve heating with temperature regulators to improve dosing capability for viscous lubricants
- Circumferential dosing possible on the inner and outer diameter
Spray film dosing: apply lubricants as a spray film across a wide area
Spray dosing valves are always used if you do not want to apply the lubricant to small individual areas. These include guide elements such as sunroofs, kinematics for grab handles and storage compartments, as well as blinds for centre consoles. But also in the electrical industry for conductive grease or in locks and fittings.
Advantages of spray dosing valves & impulse spray valve
- Combination of repeatable precision and flat lubricant application
- Full process monitoring by SOMA dosing inspection system
- Minimised over spray
- Application-specific nozzles made by SOMA
Process monitoring for lubricant dosing
In certain sectors, there are stringent demands. Find out how to ensure traceability and zero-defect quality in the grease dosing process step in an automated way.
Dosing inspection systems: monitor and document dosing quantities in production
Impurities or air pockets in the lubricant influence the dosing process and can lead to poor results. A dosing inspection system automatically and reliably detects and documents poor dosing results. In this way, affected products can be identified and can be documented and handled accordingly to maintain zero-defect quality and traceability.
Advantages of dosing inspection system
- Complete real-time monitoring of the dosing
- Process monitoring and documentation using a piezo pressure sensor at the nozzle outlet
- Can be calibrated using a web interface or machine control
- Digital I/O signal to higher-level control
- Automatically determines the process position using teach mode
