flowplus pressure sensor with sizesThe flowplus pressure sensor – physical principles and function
PDF-File 261 KB

Sensors (from the Latin “Sensire”) are devices by means of which it is possible to detect physical or chemical properties of materials. As human beings, we are not able to perceive these properties accurately (e.g. pressure), without technical assistance, and therefore only estimate them. For this reason, measuring devices in the form of sensors, transform these properties into readable quantities which can be processed further. Pressure sensors are measuring devices for recording pressure as a physical quantity. Such sensors can be found in various aspects of life. >>more

Dosing and filling applications with progressive cavity pumps: In the field of dosing and filling in the pharmaceutical industry, one usually thinks of water-like, non-viscous products such as solutions used for injecting. For the most part, these can be filled with a high degree of process reliability using hose pumps, rotary piston pumps and time pressure systems. However, special niche products such as suspensions or gels and ointments place different demands on the filling technology. Which are therefore better served e.g. by the ViscoTec Pharma Dispenser based on the progressive cavity principle. >>more

abrasive-medien-dosierenComparison of different metering pumps
PDF-File 884 KB

What characteristics are required of a metering pump that is to process highly viscous and abrasive media that are sensitive to shear with a high degree of process security and, at the same time, tolerate changes in the flow properties of these media? The solution: a metering pump in accordance with the positive displacement principle. A progressive cavity pump (PCP for short) is a well-known example of a pump of this type. A PCP combines the properties of pumping the medium with low levels of both wear and friction, resulting in a long service life and increased energy efficiency. >>more

Plastics: Fillers, anti-friction properties & wear
PDF-File 280 KB

Caused by the high requirements on components subjected to electrical, mechanical or thermal stress in various industries, the combination of diverse properties in the same plastic material is vital. Achieved by the addition of multifunctional fillers, the corresponding procedure is identified as additive applications. The high share of fillers and the corresponding abrasiveness of these additives place huge demands on the processing dosing technology. Against this backdrop the subsequent white paper depicts the need for additives as well as the process impact on the dosing of highly filled polymers. >>more

semisolid-pharma-abfuellen-webFilling pharmaceuticals that are viscous or contain solids
PDF-File 165 KB

Conventional filling technologies such as piston or peristaltic pumps reach their limits when filling small quantities of viscous, medical or pharmaceutical products – such as gels, ointments, hyaluronic acid and polymers – with precision. Solids and abrasive products are used to be effect in these types of pump. It is exactly for these types of application that filling pumps using the endless piston principle are particularly suited. >>more

salatmarinadeFilling of viscous liquids (Food & Cosmetics) in tubular bags
PDF-File 192 KB

The demand for small packaging sizes and sample packages has dramatically increased during the last years. According to the Confederation of German Food Industry this trend will still grow in the next years. Therefore the process-safe and precise filling of liquids in tubular bags is getting more and more important. Complete machines and systems which are using filling systems based on the endless piston principle could fulfil the high requirements… >>more
