Diaphragm vacuum pump MD 1 VARIO-SP

oil-free24 Vdcthree-stage

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 extraordinarily silent and vibration-free, with an extended lifetime for its diaphragms. The MD 1 VARIO-SP is an excellent choice for continuous, contamination-free evacuation and pumping of non-aggressive gases. The motor speed is either fixed or can be adjusted externally via electronic control signals for adaptation to process requirements. The pump is extremely compact and mountable in any position and therefore the ideal built-in or system pump. Customized versions of these pump types are available on request. Performance features contamination-free pumping and evacuation high flow rate even near ultimate vacuum variable speed: Fast pump down at high motor speed, with reduced speeds to maintain vacuum very powerful and extremely compact; whisper quiet and ultra-low vibration, especially at low speed customized versions available
