These pumps offer reliable operation even for such critical industrial applications as drying processes, metallurgical processes or resin potting and casting systems – either as a standalone pump or as a backing pump in our roots pumping stations or turbo pumping stations. The use of a magnetic coupling minimizes maintenance requirements and leads to considerable cost savings per pump and maintenance interval. Reliable, clean, low maintenance. Compact design - Excellent performance data. Integrated safety and gas ballast valve. Various motor voltages afford worldwide employment. Contain no non-ferrous metals. M = Magnetically coupled
