MD 4 VARIO-SP

VARIO-SP^TM diaphragm pumps are extremely compact and ideal for continuous, oil-free pumping of non-aggressive gases at good ultimate vacuum. Due to their variable speed drive system they are much more flexible to use than the corresponding fixed speed pumps. The brushless 24V DC motor (maintenance-free) enables easy integration of the pump into other equipment and operation independent of line voltage. The pump design is distinguished by extraordinarily silent operation and an extended diaphragm life. The three-stage MD 4 VARIO-SP diaphragm pump offers exceptionally high flow rate and excellent ultimate vacuum.

Performance features

• contamination-free pumping and evacuation
• high flow rate even near ultimate vacuum
• variable speed: Fast pump down at high motor speed, with reduced speeds to maintain vacuum
• very powerful and extremely compact; whisper quiet and ultra-low-vibration, especially at low speed
• choose the MZ 2 VARIO-SP for reliable, variable pumping, or the MD 4 VARIO-SP for greater vacuum capacity and higher flow rates
