VARIO®-SP chemistry diaphragm pump MD 1C VARIO-SP

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). 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 adaption to process requirements. For chemistry applications all major parts of the chemistry design pump MD 1C VARIO-SP in contact with pumped media are made of chemically resistant fluoroplastics. Both pump types are extremely compact and mountable in any position and are therefore the ideal built-in or system pump. Customized versions of these pump types are available on request.
Chemistry diaphragm pumps from VACUUBRAND for aggressive gases and vapors are available in the basic version, with two-point or VARIO® control.
Chemistry diaphragm pumps from VACUUBRAND for aggressive gases and vapors are available in the basic version, with two-point or VARIO® control. Their construction with fluoropolymers makes them very resistant to chemical vapors from inlet to exhaust.
• 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
