Suction pump MD 1 VARIO-SP

laboratoryelectricdiaphragm

Overview

• Contamination-free pumping and evacuation
• High pumping speed even near ultimate vacuum
• Variable speed (VARIO®-SP): fast pump-down at high motor speed and reduced speeds to maintain vacuum
• Compact design with low noise and very low vibration, especially at reduced speed
• Customized versions and integration options available

Product description
The three-stage diaphragm pump MD 1 VARIO-SP with VARIO®-SP variable-speed drive delivers higher effective pumping speed and improved ultimate vacuum compared with equivalent fixed-speed models. The maintenance-free brushless 24 V DC motor enables easy equipment integration and operation independent of mains voltage. The pump offers low acoustic emission, minimal vibration and extended diaphragm service life, making it suitable for compact installations and inline integration.
