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.
Gear pumps for the chemical industry, process pumps
Optimized metering pumps for chemical processes – low-pulsation gear pumps with high chemical resistance and precise metering
Paint metering pumps can also be used for robot applications. Even at short flushing cycles these pumps show excellent flushing results.

MarSpin – Planetary Spinning Pumps
Planetary spinning pumps – representing the heart of a spinning plant. They are used in large quantities. Tight production tolerances of the pumps, reliability and long lifetime are the key words for a high-quality yarn and customer satisfaction. Feinpruef spinning pumps of Mahr Metering Systems do guarantee to withstand toughest process conditions to finally spin and deliver a first-class quality yarn to the winder.
The special feature of planetary spinning pumps is the dosing of a material flow into up to 64 equal individual streams. These pumps are not only used for production of many different synthetic fibre and yarn, of that, for example, micro fibre textiles, tights, spandex, protective clothing and even astronautic overalls will be made. Planetary spinning pumps are also used for applications of dosing glue & adhesives and almost all kinds of fluids.

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
- rotary shaft seal
- labyrinth seal
- mechanical seal
- magnetic coupling
Atex Directive 2014/34/EU
A version according to the Atex directive is available for the pump as well as for the drive.
Heating or cooling for the gear pumps Heating or cooling can be provided electrically as well as by the thermal fluid.
