Gear Metering Pumps for Paint Application - MarCoat
EN

The MarCoat design is suitable for metering different paints and colors. These special pumps can be cleaned easily in a very short time period. Due to different sizes and connection designs these pumps are offering a wide range of mounting options for the whole paint industry. Also these pumps are best suitable for roboter applications.

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 plate
    • with mounting block
  • Coupling
    • curved tooth coupling
    • cardan shaft
    • all-steel coupling
    • magnetic coupling
  • Motor
