DUOLINE™ Rotary vane pumps for all applications in the low and medium vacuum range

The two-stage high-performance rotary vane pumps cover all low and medium vacuum applications, achieving pumping speeds of 1.25 to 300 m3/h. Applications range from mass spectrometry or optical coating to critical industrial applications such as drying processes, metallurgical processes or resin casting systems. The pumps ensure high operational safety - preferred as a backing pump in a Roots or turbo pumping station. The integrated, hydraulically controlled high-vacuum safety valve ensures high operational safety. An integrated connection point for oil return simplifies retrofitting of an...

Rotary vane pumps for all applications in the low and medium vacuum range Standard Magnetically coupled Corrosive 1 PFPE operating fluids must be ordered separately. Our standard rotary vane pumps are generally filled with mineral oil and cover a broad range of uses in practically all fields of vacuum technology. In contrast to the standard pump, these products have a frictionless magnetic coupling. Oil leakage from a wear-prone conventional shaft seal is ruled out in these models. ■ No Maintenance at the shaft feedthrough -lower maintenance costs ■ No oil leaks - environment-friendly These...

Corrosive magnetically coupled By using the magnetic coupling, the integral leak rate of these pumps is less than 1 · 10-7 Pa m3/s. This maximizes the operating reliability in corrosive applications.1) Due to the state-of-the-art drive, the DC version is even more energy-saving and lighter. With its brushless 24 V DC drive, the pump is perfectly suited for mobile applications, for example, in analytical applications. Furthermore, the temperature range is extended in comparison to common rotary vane pumps. The DC drive operates at -20°C; therefore it can be operated in vehicles. ATEX version...
