- Chemical gear pumps of the CHEM series are extremely flexible in design and can be offered in various variants and configurations thanks to a modular system.
- Chemical gear pumps for differential pressures up to 120 bar, suction pressures vacuum up to 15 bar
- Chemical gear pumps for temperatures up to max. 500 °C in combination with a magnetic coupling.
- Chemical gear pumps for viscosities up to 1,000,000 mPas or higher.
- Chemical gear pumps made of stainless steel, ceramics and special materials
- Chemical gear pumps with throughput from 20 l/h to 170,000 l/h
On request, our fitters can also install the pumps directly in the system and are on site during commissioning. For the CHEM series in the standard version, a comprehensive modular system with a large number of different materials for the individual components is available.

Chemical gear pumps in special pump construction
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°C.
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.
