Abstract (en)
Gear pump assembly (1) comprising at least two independently-driven gear pumps (8a,b) in a single housing (2) arranged collaterally with respect to the rotational axes of their respective drive gears (5a,b), either in the same plane or at an angle to each other. This is significantly more compact than existing solutions of multiple single gear pumps or coaxial gear pumps in a single housing, and gives great flexibility in design and of pumping parameters.
