VARIO-SP TM diaphragm pump
MD 1 VARIO-SP and 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 extraordinarily silent and vibration-free, with an extended lifetime for its diaphragms. For
exceptional chemical resistance of the pump's internal flowpath, it is also available in a chemistry design (MD 1C
VARIO-SP).

2 mbar
The MD 1 VARIO-SP is an excellent choice for continuous,
contamination-free evacuation and pumping of nonaggressive
gases. The motor speed is either fixed or can
be adjusted externally via electronic control signals for
adaptation 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.
