The MarFin spin finish pumps meter spin finish very precise. Especially for the fast spinning process the use of our MarFin pumps to apply liquids like antistatic finish, adhesive additives or other additives, can avoid fibre breaks or electrostatic charging. The fibres get a better elasticity as well as better properties for the further processing. An exact metering of the finish for each product stream is assured. Furthermore MarFin pumps currently find a lot more applications in different industries to meter for example low viscous liquids like water, organic solvents, parfums and oils.
The product range for gear pumps can not be completey described due to the huge diversity of designs, as well as the application fields. Please contact us in case of requirement. We are pleased to provide detailed consultation and optimal solutions for you.

Coating
Coating technologies take a significant key position in the development of new products. The various coating technologies enlarge the application possibilities of the used base materials. Furthermore, a coating reduces friction, wear and corrosion. In principle, all the named materials can be coated depending on the specification.
DLC-Coating
Diamond-Like Carbon (DLC) improves the properties:
- high surface hardness
- high wear protection
- smaller coefficient of friction
- better corrosion reduction to agressive 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 Mahr / Feinpruef specific high discharge accurancies)
- high economic efficiency through longer endurance and improvement of the technological properties
DLC- coatings are biocompatible and facilitate also the use in the food industry and in the medical field.
The pump arbor are available in following types:
- carrier shaft
Gear pump with motor
- Base frame
- Coupling

Atex Directive II2Gc
A version according to 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.
