Dosing pumps are used in many applications, in laboratories and within industry. Often we see the needs, when we require dose liquids under specific conditions:
- High pressure dosing (reaction chambers, aparatures)
- High temperatures dosing
- Injection of reactive substances
- Dosing of viscous media
For all above mentioned applications it is possible to use technology that has been proven in the area of high performance liquid chromatography (HPLC). These are double-piston pumps AZURA (Knauer), which use sphire pistons enabling precise continuous dosing under high pressure. These pumps can work with flow of 0,01 to 1000 ml/min, under temperatures of -10°C to +120°C and with viscous media up to 1000 mPa.s.
The pumps can be especially equipped so they can be used in specific application like hazardous areas.
Nice example of use of AZURA pumps is dosing of sulphur trioxide in production of methanesulfonic acid (MSA).
Pump head are available in following materials:
- Hastelloy C-276
- Stainless steel
- Stainless steel/Titanum
