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 life time 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.

This range of gear metering pumps was originally designed for the spinning of finest filaments – the typical first generation spinning pump. As a "real" spinning pump nowadays, this design is only used for very special applications like producing of aramide and carbon fibers. For all the other kinds of industries and applications this design is typically used as a standard metering pump with almost no limits.

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.

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.

Inline gear metering pumps are single stream pumps and directly installed in the product lines, eliminating the need for an additional pump block. The design allows the medium to pass the pump without any flow direction changes, The inline gear metering pumps can be used for all applications. Especially under high pressure ratios, they perform with excellent process stability.

Discharge pumps with low product shearing ensure an optimal discharge of viscous polymer melts of reactors. The discharge pumps can be supplied both liquid and electrically heated. Booster pumps are usually performed as an inline pump. They are mainly used after an extruder or a discharge pump. They create appropriate filling pressure for the following pumps or tools.

Thanks to its lateral drilling, the Dosimar gear metering pump can be integrated directly into a wide variety of installation situations. It is often installed in meter mix machines, for example. The so-called mounting gib allows easy mounting of the pump in the machine. In addition to dosing polyurethane components like isocyanates and polyols, various resins and other liquids, this pump series is also used in the production of various fibres such as aramid and PAN. In addition, this pump meters additives in the polimerization process.

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.
