Dosing Devices
Dosing Devices
Chemical pumps are used in WITTE metering pump systems. Pumps of the CHEM series are exclusively designed and assembled at the Tornesch site. In this way, we guarantee the highest reliability and quality. On request, we offer a comprehensive spare parts service for all our series.
- Dosing solutions for throughputs from 1kg/h to 600 kg/h
- Dosing solutions for low viscosities up to 200 mPas
- For the chemical industry, WITTE offers dosing pumps and dosing technology as individual solutions or complete dosing solutions with various control options.
- Dosing solutions for differential pressures up to 120 bar
In addition, we also install the pumps directly at our customers' facilities. For dosing pumps we also offer a comprehensive maintenance and repair service.
We have spare parts for many pump sizes in standard designs in stock at our branches in Germany, the USA or China. In the event of damage, our service technicians can be on site within 24 hours in Europe and within 48 hours in most countries outside Europe.

Special pump construction for dosing units
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.
