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.
MarChem – Gear Metering Pumps
Precise and low pulsation metering of liquids – this is the need in many industries. For this purpose, Mahr provides gear metering pumps which stand apart due to their excellent efficiency even at low viscosity at a significant counter pressure and achieves low-shear metering of liquids.
Years of experience as well as successful completion of various projects has resulted in an evolution from a bare pump to the development of a whole metering system. By means of modern sensor technology it is also possible to continuously monitor processing values of gear metering pumps like pressure, temperature, flow rate, leakage etc. Thus, production breakdowns can be prevented. This is because monitoring process parameters is not only common, but a must in many areas.
What advantages offer Mahr gear metering pumps compared to other alternative pumps?
- low operating and maintenance costs
- low maintenance requirements
- each single part can be replaced separately
- long durability due to technically customized layout for user-specific operating data

Coating
Coating technologies take a significant key position in the development of new products. The various coating technologies enlarge the application possibilities of the base materials. Furthermore, a coating reduces friction, wear and corrosion. In principle, all named materials can be coated depending on the specification.
Diamond-Like Carbon (DLC) improves the properties:
- high surface hardness
- high wear protection
- smaller coefficient of friction
- better corrosion reduction to aggressive media
- higher chemical resistance / stability
- non-stick effect (reduced adhesion of polymers and other materials)
- high temperature firmness to 250°C
- excellent accuracy to size (no change of the high discharge accuracies)
- high economic efficiency through longer endurance and improvement of technological properties
- biocompatible, allows the use in the food industry and in the medical field
Sealing systems for the gear pumps
- stuffing box seal optionally with barrier liquid
- rotary shaft seal optionally with barrier liquid
- labyrinth seal
- mechanical seal, single, double and optionally with sealing liquid
- magnetic coupling
