MD 1C VARIO-SPVARIO®-SP chemistry diaphragm pump
Overview
- contamination-free pumping and evacuation
- high flow rate even near ultimate vacuum
- VARIO®-SP = variable speed: Fast pump down at high motor speed, maintain vacuum with reduced motor speed
- very powerful and extremely compact; whisper quiet and ultra-low vibration, especially at low speed
- MD 1C VARIO-SP in chemistry design, with gas ballast valve and outstanding chemical resistance and superior vapor tolerance
Ultimate vacuum
2 mbar
Ultimate vacuum with gas ballast
4 mbar
Max. pumping speed 50 Hz
1.8 m3/h
VARIO®-SP chemistry diaphragm pump in action
The three-stage MD 1 VARIO-SP diaphragm pump with its variable speed drive system attains significantly higher pumping speed and a better ultimate vacuum than the corresponding fixed speed pump. The brushless 24V DC motor (maintenance-free) enables easy integration of the pump into other equipment and operation independent of line voltage. The pump is particularly silent and vibration-free, and has an outstanding lifetime of its diaphragms and valves. For exceptional chemical resistance of the pump´s internal flowpath it is also available as a chemistry design version (MD 1C VARIO-SP).
