High temperature dosing: handling temperatures up to 120°C

Sometimes the supply of media or starting materials for a chemical reaction needs to be heated to properly meet the conditions of the process. This is where standard high pressure pumps can reach their limits. KNAUER dosing pumps withstand moderate liquid temperatures and can be equipped with thermally decoupled pump heads even for elevated temperatures.

It is also possible to equip the pump with a pump head heating device for temperature sensitive applications.
