MD 1 VARIO-SP from BRAND (BrandTech Scientific). contamination-free pumping and evacuation
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.
Key Features
variable speed
Fast pump down at high motor speed, with reduced speeds to maintain vacuum
