Einsatzbereiche von Mahr Maschinen
Proven use for decades to spin finest yarn: planetary spinning pumps are the heart of every synthetic fibre spinning plant.
Spin finish dosing pumps do not only meter preparation fluids. They can also be used for the consistent dosing of water, perfume or even oils.
There are almost no limits to the use as a dosing pump in various industries. As a spinning pump it is only used for special applications.
Predominantly used in spinning and adhesives technology, they offer the possibility of realizing two flow rates with minimal space and one motor drive only.
Product bores which are on both sides of the pump body allow the pump to be integrated directly into the production line.
They can be used for all applications. Direct installation in the product line does not require an additional clamping block.
Discharge pumps ensure gentle discharge of polymer melts with low product shear. Booster pumps ensure a defined process pressure for downstream tools such as dies or extruders.
For highly accurate, low-pulsation dosing of liquids. The gear metering pumps achieve an efficient performance even at low viscosity and back pressure.
Paint metering pumps can also be used for robot applications. Even at short flushing cycles these pumps show excellent flushing results.
Solutions for material preparation, conditioning and supply to the meter mix dispense machine.
The mixing takes place exclusively through the flow movement of the components and the geometry of the mixing element.
The components are mixed by a rotating element in a mixing chamber.
The mixing takes place through the flow movement of the components in cooperation with the geometry and rotation of the mixing element.

Nowadays people hear and read a lot about the materials, often in their common abbreviations PU or PUR. But what exactly are polyurethanes?In simple words: Plastics, whose applications are extremely versatile. They can be encountered almost everywhere in our everyday life, in the living room as armchair cushion, on the way to work in the car or public transports, as well as in many technical applications. And how are polyurethanes made? As general initial substances are polyols, isocyanates and catalysts. The polyaddition reaction of these substances produces polyurethane, which gains its specific properties through different crosslinking and different initial substances respectively to its application. In general, polyurethanes can be classified in foams and cell-free PUR elastomers.
Polyurethanes are adjustable and therefore they can be assigned to fulfil specific properties
