Inline Gear Metering Pumps

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.

The pump drive connection is available in the following types:

  • shaft type
  • 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
    • servo motor / 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
  • labyrinth seal
  • mechanical seal
  • magnetic coupling

ATEX Directive 2014/34/EU
A version according to the Atex directive is available for the pump as well as for the drive.

Heating or cooling of the gear pumps Heating or cooling can be provided electrically as well as by the thermal fluid.
