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.
MarFin – Spin Finish Metering Pumps
Liquids like antistatic finish, adhesive additives or other additives can avoid fiber breaks or electrostatic charging during the fast spinning process. The fibers get a better elasticity as well as better properties for the further processing. MarFin meter spin finish very precisely, which ensures exact metering of each feed stream.
Furthermore, MarFin pumps currently find a lot more applications to meter low-viscosity media such as water, organic solvents, perfume and oils.

The drive units are designed according to the operating conditions.
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
