Laboratory vacuum pump MD 1C VARIO-SP

diaphragmmulti-stageoil-free

Overview

• Contamination-free pumping and evacuation
• High pumping speed even near ultimate vacuum
• VARIO®-SP variable-speed drive: fast pump-down at high speed, maintain vacuum at reduced speed
• Compact design with low noise and low vibration, especially at low speed
• Chemistry version (MD 1C VARIO-SP) with gas ballast valve for improved chemical resistance and vapor tolerance

Product details
The three-stage MD 1C VARIO-SP chemistry diaphragm pump features a variable-speed drive that provides higher pumping speed and a better ultimate vacuum than comparable fixed-speed pumps. The brushless 24 V DC motor is maintenance-free and allows easy integration into equipment independent of mains voltage. The pump offers low noise and vibration and extended lifetime of diaphragms and valves. The chemistry design uses materials and a gas ballast valve to increase tolerance to condensates and aggressive vapors.
