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.

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
