- BOXER 22KD Miniature Diaphragm Pump Series
22KD Series
The 22KD series is a double headed miniature diaphragm pump designed for a wide range of applications including gas sampling, gas detection and monitoring. This pump series is of certain interest for applications requiring flow above 2 l/min in a compact envelope. Additionally, when run at lower speeds with a flow of 1 l/min and below, sound and vibration is reduced to levels which cannot be matched with a single headed pump.
Like all other pumps in the Boxer range, this series of miniature diaphragm pump can be customised to specific requirements. Diaphragms are available not only in different materials but also different thicknesses and profiles depending on the exact needs of the application. Likewise eccentrics from 0.5 to 0.85 mm can be configured.
This series is available with either iron core or BLDC motors.
› Flow rate to 2.6 l/min
› Low sound and vibration
› BLDC motor option with speed input for ultimate flow control
› Compact and versatile
› Antivibration mounting foot available
Flow control is available in combination with PWM Flow Controller.
