Gear metering pumps for silicones |
When sealing with silicones the accuracy of the melt flow is the major requirement. Precision metering does not only presuppose the fast and reproducible operating point setting, it also requires a low-pulsation feed-in of the conveyer medium. Once again, Oerlikon Barmag's gear metering pumps offer considerable advantages since the gears are correspondingly designed and precisely manufactured. Adding to the requirement of highest accuracy, metering pumps in silicone applications have to deal with high-viscosity media and high temperatures. Oerlikon Barmag pumps allow for viscosities between 1 Pas - 150 Pas, back pressure up to 200 bar and operating temperatures up to 230 °C.

Since 1922, Oerlikon Barmag’s gear metering pumps have been used worldwide as process engineering components in applications involving chemicals, plastics, colours & dyes as well as PUR.
These dosing pumps are used mainly for highly precise metering of chemical fluids. Accurate metering at high pressure is guaranteed even under the most difficult operating conditions involving light and toxic media.
