OPERATION

Meterflo pumps are available with a special coupling that
allows easy replacement of older Meterflo pumps. (See
ordering information for details).
As the gears come out of mesh, oil
is drawn into the suction side (S) of
the pump, filling the spaces between
the gear teeth. As the gears rotate,
oil is carried between the teeth and
the gear housing until it reaches the
discharge port (D). As gears mesh,
they force out the oil.
