2KD Series

The 2KD series is a double headed miniature diaphragm pump designed for gas sampling and gas detection. 2 heads allows flexibility of paralllel or series connection to extend the pressure / vacuum capability or to pump 2 totally separate gasses.

Iron core and coreless DC motor options are available in this series.

› Flow rate to 3.7 l/min
› Minimum power power consumption
› Choice of wetted parts
› Low temperature operation

This series is also available in a single head configuration (2K).

Flow control is available in combination with PWM Flow Controller.
