Brushless DC motor as drive (option)
The micro annular gear pump mzr-4622 can alternatively be driven with a
brushless DC-motor. It is characterized by higher dimensions and a wider speed
range, which covers entirely the speed range of the micro annular gear pump
and shows a longer service life than a brushed DC-motor.
