Special pump construction for the chemical industry
In addition to standard chemical pumps, we also supply special pumps according to customer requirements. We take over the complete engineering as well as the research and development work. On request, we can also carry out test runs close to the real operating point on our test bench.
As special chemical pumps to customer specifications, for example, we have developed a ceramic pump for pumping high-temperature brine that operates at temperatures above 500 °C. This pump is designed for use in the production of brine at high temperatures.
We have also developed pumps for extreme design pressures of up to 575 bar or pumps for pumping liquid sulphur in addition to many other applications on customer order. Many of these pumps have significantly improved the process and have been used for years under the most extreme conditions with absolute reliability.
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.

Conversion service for chemical pumps
As a manufacturer of chemical pumps, we have specialised not only in the supply of our own products but also in the conversion of products from other manufacturers. Thanks to our many years of experience and expertise, we are able to convert gear pumps from other manufacturers in such a way that a significant increase in delivery volume per revolution can be achieved while maintaining the same footprint and flange connections. This represents a cost-effective increase in capacity without the need for time-consuming conversion of the system.
