VARIO®-SP 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 extraordinarily silent and vibration-free, with an extended lifetime for its diaphragms.
