High-quality metrology for quality control in the measuring room, production, incoming goods and development.
Gear Metering Pumps & Meter Mix Dispense Machines with highest accuracy for processing liquids and pastes.
High-precision rotary stroke bearings for backlash-free linear and rotational movements for use in machine and device construction.
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.

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.
MarSpin – Double-Outlet Gear Metering Pumps
Turning one into two: The classic single-gear metering pumps have evolved into double-gear dosing pumps. Depending on the application, you can choose between two different versions: three-gear metering pumps with one housing level or stacked design in two layers.
The double-gear metering pumps from Mahr are mainly used in spinning and ashesive technology. With a small footprint they offer the opportunity to realize two flow rates by using only one drive.

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 of the gear pumps
- stuffing box seal
- rotary shaft seal
- labyrinth seal
- mechanical seal
- magnetic coupling
ATEX Directive 2014/34/EU
