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.
Discharge and Pressure Increase Pumps
Discharge pumps with low product shearing ensure an optimal discharge of viscous polymer melts of reactors. The discharge pumps can be supplied both liquid and electrically heated. Booster pumps are usually performed as an inline pump. They are mainly used after an extruder or a discharge pump. They create appropriate filling pressure for the following pumps or tools.
| Material | Material properties | Field of application | Permissible operating temperature max. | Permissible cleaning temperature max. |
|---|---|---|---|---|
| F24 | molybdenum, tungsten, vanadium and chromium alloyed high speed steel for non-corrosive applications |
| 450°C 840°F | 550°C 1020°F |
| N19 | high chromium alloyed stainless steel, additions of molybdenum and vanadium for corrosive applications. |
| 180°C 356°F | 200°C 392°F |
