Mechanical seal pumps for the chemical industry

In addition to standard mechanical seal 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 at 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 that operates at temperatures above 500 °C. The pumps are also available in a variety of other versions.

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.
