P Series

Thanks to magnetic coupling, these pumps operate contact-free and wear-free. This is ideal for toxic, environmentally hazardous or aggressive media. They are designed for high pressures and can be controlled very precisely.

The P series can pump media up to a temperature of 60 °C. Under the designation P-EX, we also offer an ATEX-certified version for use in ATEX zone 2. more ...
