VARIO-SPTM diaphragm pump MZ 2 VARIO-SP

MZ 2 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.

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
