MarFin Spin Finish Metering Pumps

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 fiber breaks or electrostatic charging. The fibers get a better elasticity as well as better properties for the further processing. Furthermore, MarFin pumps currently find a lot more applications to meter low-viscosity media such as water, organic solvents, perfume and oils.

The pump drive connection is available in following types:

  • shaft type

Gear pump with motor

  • Base frame
  • Coupling
    • curved tooth coupling
    • magnetic coupling
  • Motor
    • asynchronous gear motor
    • servomotor / servo gear motor
    • synchronous geared motor

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

 

Sealing systems of the gear pump

  • stuffing box seal
  • rotary shaft seal
  • magnetic coupling

Atex directive

  • II 2G Ex h T6...T1 Gb
  • II 2G Ex h T6...T2 Gb

A version according to the Atex directive is available for the pump as well as for the drive.

Heating or cooling for the gear pump Heating or cooling can be provided electrically, as well as by the thermal fluid.
