Dosing
Dosing
WITTE gear pumps are used for dosing a wide variety of media. Depending on the medium, temperature, pressure and viscosity, different pump series are used.
- Dosing of media with temperatures up to 500 degrees
- Dosing of viscosities up to 1.000.000 mPas
- Dosing with gear pumps made of stainless steel, ceramics and special materials
- Dosing with gear pumps with throughputs from 20 l/h to 170,000 l/h
- Dosing with gear pumps with delivery volumes from 0.2 ccm/rev to 12,000 ccm/rev
- Dosing at suction pressures from vacuum to 15 bar
- Dosing with special pump according to customer specification
- Dosing with gear pumps at differential pressures up to 120 bar
WITTE pumps dose polymer melts in the manufacturing process, additives in extrusion processes or chemicals of all kinds.

Special pump construction for dosing
In addition to standard chemical pumps, we also supply special pumps according to special customer requirements. We take over the complete engineering as well as the research and development work.
We can also carry out test runs close to real operating points on our in-house test bench.
We have already realized special chemical pumps according to customer requirements in a wide variety of designs. For example, ceramic pumps for pumping high-temperature brine working at temperatures above 500 degrees Celsius.
Pumps for extreme design pressures up to 575 bar are also part of our portfolio.
The process is often significantly improved through the use of these pumps.
If you have any questions regarding the development of special pumps or the use of special materials, please contact our materials expert and sales manager Mr. Carsten Pump.
