Diaphragm vacuum pump MD 1C VARIO-SP

oil-free24VDCthree-stage

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 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).
