b.
Centrifugal Dump. The pumping capability of the pumping assembly is provided by the pump unit contained within
the assembly. This pump is a centrifugal type pump which means that it provides its pumping action by using an
internal rotating impeller to sling the fuel from the center of the impeller to the outer edges of the impeller as it
rotates. This throwing action, technically known as centrifugal force, causes a vacuum in the inlet pipe of the
pump to draw more fuel into the pump. The fuel which has been forced to the outer edges of the impeller are
further forced into the outlet pipe of the pump to eventually leave the pump unit.
