Brushed DC-motor without encoder as mzr-7242
The micro annular gear pump mzr 7242 can be powered alternatively with a
brushed DC-motor. This has a smaller design and a wide speed range, which
include the entire speed range of micro annular gear pump covers and has an
increased life span compared to a DC-motor with brushes.
