Inline gear metering pumps are single stream pumps mounted in-line with the tubes. This type of pump is used for several applications. Because of the in-line mounting no additional pump block is necessary.
Mahr Inline gear metering pumps are available in different technical designs and there are too many variations to have real standard types. Therefore please contact us in order to get the right proposal for your application.

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 drive connection is available in following types:
- shaft type
- plug type

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.
