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.

2K - nK meter mix dispense machine for high material flow rates
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.
The challenges in thechemical and process industries
In the chemical industry, precision is not just a question of efficiency: it determines safety, quality, and cost-effectiveness.
Conventional pumps quickly reach their limits, whether due to metering instability, leaks with aggressive media, high maintenance requirements, or unsuitability for highly viscous and temperature-sensitive substances.
Our solution: High-precision gear pumps with global expertise
Our pump technology has proven itself for decades, for example in the production of synthetic fibers:
under high pressure, at high temperatures, and with extremely viscous media. The continuous further development of the
pumps has opened up their use for a growing range of applications. We are now applying our experience and expertise,
as well as the proven precision and robustness of our pumps, to the process and chemical industries.
