Product Properties

All ranges of construction are chemical resistant and are especially suited for the transmission of highly pure and corrosive media in the following performance range:


  • Volume flow rates up to 500 l/min [30 m3/h] [132 US-Gal/min]
  • for discharge heads up to 40 m [131 ft].


Various designs comply with the European Union ATEX directives for application in explosive atmospheres.

Drive motors

High-quality electric motors made in Germany. Pumps are generally equipped with three-phase motors with a performance range of 0.12 to 5.5 kW. Alternating current, explosion proof and pressure-tight encased motors can be supplied on request.
