Bubble-free filling of oil dampers

Monday, November 27th, 2017 von admin

Filling of oil dampers in low-volume and pilot production is mostly manual work. There is a lot of potential for improvement by a compact, flexible dosing system which includes a micro metering pump. This self-priming micro annular gear pump can work without an application of compressed air to the reservoir.

On the one hand, this saves the cost of compressed air including the necessary devices and, on the other hand, avoids the introduction of compressed air into the silicone or hydraulic oil. The medium can be filled bubble-free, gently and without loss of quality.
