2 heads allows flexibility of paralllel or series connection to extend the pressure / vacuum capability or to pump 2 totally separate gasses.
Like all other pumps in the Boxer range, this series can be customised to specific requirements. The components are produced in a wide variety of materials providing compatibility with a wide range of applications.
This series is available in iron core and coreless motor options.
› Flow rate to 2.0 l/min
› Exchangeable heads
› Panel mounted
› Robust and compact design
This series is also available in a single head configuration (12K).
Flow control is available in combination with PWM Flow Controller.
