Abstract
Example fluid circuits (e.g., within aircrafts) include first and second pump assemblies. The first pump assembly has an electric motor and a first fluid pump. The first fluid pump is coupled to the electric motor and has a case drain port that is in fluid communication with a case drain region of the first fluid pump. The second pump assembly is powered by hydraulic pressure from the first fluid outlet of the first fluid pump and functions to augment flow through the case drain region of the first fluid pump.
