A fluid pump includes a pump head having an inlet for receiving fluid at a first
pressure and an outlet for outputting fluid at a second pressure greater than the
first pressure. Pressurized fluid is directed through a first passage to the outlet
without the pressurized fluid leaving the pump head prior to reaching the outlet.
A second passage directs pressurized fluid to a fluid circulation path which is
at least partially external to the pump head with the fluid circulation path terminating
adjacent the outlet. Pressurized fluid passing through the first and second passages
is directed to the outlet without being re-pressurized by the pump head. The first
and second passages are in opposed relation to one another to provide balancing
of thrust produced by the flow of pressurized fluid through the passages. An electric
motor drives the pump head. The fluid circulation path may include portions of
the electric motor.
