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.


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 drive connection is available in following types:

  • plug type

Gear pump with motor

  • Base plate
    • with mounting block
  • Coupling
    • curved tooth coupling
    • cardan shaft
    • all-steel coupling
    • magnetic coupling
  • Motor
    • asynchronous gear motor
    • servomotor / servo gear motor
    • synchronous gear motor

The drive units are designed according to the operating conditions.

Sealing systems for the gear pumps
