UMIX® universal mixers
Original design Werner & Pfleiderer
UMIX® – Universal mixer: The specialist for demanding compounds
The UMIX® series comprises high-performance universal mixers with a working volume ranging from 0.25 litres to 4,300 litres, making them suitable for applications ranging from laboratory use to large-scale industrial production.
The UMIX® is ideally suited for mixing and kneading low- to high-viscosity materials in sectors such as the rubber, silicone, plastics, paints, adhesives, pharmaceutical, cosmetics, food and general chemical industries.
Versatile application: Suitable for a wide range of materials and processes.
Flexible discharge options: Product discharge via trough tilting, discharge screw or bottom valves. The swivel angle of at least 110° aids in the discharge of the mixture.
Process control: Temperature-controlled troughs, rotors, discharge screw and screw tubes enable precise temperature control of the mixing process.
Service & spare parts: Spare parts and services such as inspections, commissioning and installation are available for our own machines as well as for universal kneaders from the brands ‘Werner & Pfleiderer’ and ‘Coperion’
Together we find a better way.
The best and most efficient rubber and plastics processing solutions.
All the facts about the UMIX® at a glance:
Two mixing and kneading blades arranged in parallel
Water or heat transfer oil temperature control of the mixing chamber
Mixing chamber made of carbon or stainless steel (duplex steel on request), depending on the properties of the material being mixed
Various blade geometries – tailored to your processes
Optional: temperature-controlled blades for processing temperature-sensitive products (from UMIX® 80 upwards)
In addition to the dispersion and distribution of the ingredients in the batch process, the design of the machines allows further process steps to be carried out simultaneously during mixing, such as:
Plasticising
Homogenising
Melting
Cooling
Degassing/evaporation of volatile components
Evaporation
Dissolving
Reacting
UMIX® production machines are manufactured with working volumes starting from 20 litres. All machines with a working volume of 80 litres or more are equipped with individually driven rotors which, in combination with the speed control included as standard, allow the speed and friction of the blades to be freely adjusted, thereby enabling optimal adaptation to existing and future customer processes
Key advantages of the UMIX® series
1. Versatile application
UMIX® universal mixers are suitable for a wide range of industries and their specific mixing processes, such as food, cosmetics, pharmaceutical and chemical industries, as well as for PVC and silicone compounds. The range of compounds that can be produced reaches from low- to high-viscosity and from sticky to powdery/dust-dry.
2. Homogeneous mixing processes
Thanks to powerful drives and the optimised geometry of the mixing and kneading tools, combined with effective temperature control, the required homogeneity and quality of the compounds can be achieved in a short time. (This can be further improved by vacuum mixing)
3. Flexible plant design
The universal mixers can be individually integrated into existing production lines, including those with existing conveying systems – from laboratory scale to large-scale production.
4. Material compatibility
As standard, all components in contact with the product are made from high-quality, corrosion-resistant steel (1.4404 or equivalent).
5. Batch documentation
The ADVISE® control system developed by HF supports seamless process monitoring and logging for reliable quality control and traceability.
6. Maintenance-optimised original design
Thanks to the original WP design, mixers can be easily replaced or overhauled without having to completely rethink processes and recipes. This is particularly important for certified mixing processes: a new mixer can be manufactured with the exact same characteristics as the existing mixer.

Your Questions - Our Answer
FAQ
What materials can the UMIX® process?
The UMIX® universal mixer and the UMIX®-L laboratory mixer process a wide range of materials. They are mixers for the food industry, cosmetics industry, pharmaceutical industry and chemical industry, and are also paint, PVC and silicone mixers – thanks to flexible batch technology, hygienic design and adaptable mixing technology. As industrial mixers that comply with GMP and FDA standards, they are ideal for applications with high requirements for dispersion, emulsification and recipe control in laboratories, pilot plants and large-scale production.
The highly effective Sigma blades of the UMIX® cover a very wide viscosity range – from water-like to highly viscous/powdery. This makes the UMIX® one of the few mixers that can be used for mixing processes with changing viscosities.
How easy is it to clean the UMIX®?
To improve cleanability, the side wall of the mixing chamber can be opened wide enough on some models to provide good access to the mixing tools. This greatly reduces cleaning times. The two smallest laboratory mixers (sizes 0.25 and 0.75) are equipped with interchangeable mixing troughs.
What’s the link between UMIX® and Werner & Pfleiderer mixers?
Until the 1990s, the HF site in Freudenberg belonged to Werner & Pfleiderer, a pioneer and long-standing global market leader in the field of universal mixers. The UMIX® universal mixer is a continuous further development of the W&P universal mixer, which has been tried and tested for more than 140 years.
