Dosing systems in the filling of oil brakes

HAHN Gasfedern GmbH has been one of the leading companies in the industry for half a century. The company offers uncompromising quality in the development and production of gas springs, gas traction springs, double lift gas springs, lockable gas springs and oil brakes.

The special strength of HAHN gas springs provides in the development and production of innovative products, including oil brakes. Oil brakes are hydraulic dampers which are used for the even braking of feed devices, linear drive units, flaps and similar. When filling these dampers, it is important that the medium is dosed precisely, gently and without bubbles. Especially in prototype construction, as well as in pre- small and serial production, flexible solutions are required for the dosing of constantly changing media and quantities. In accordance with the extensive requirements at Hahn Gasfedern, a dosing system with self-priming micro-dosing pump was configured, for use in different application parameters.

 

Decision criteria for the dosing system including pump

  • precise and gentle dosing
  • high viscosity range that can be pumped
  • no form necessary
  • Retraction for optimum drop break-off
  • Preselection of the dosing requirement and dosing speed


Applied pump

  • mzr-7245 S in the system, consisting of filter, media supply, control system and piping
