B pump housing - sectioned - showing self-purge orifice

B pump housing with notional surface polish to show shape and detail (such a surface was not used on the actual pump casing). The casing nearest the turbine has been cutaway to reveal internal detail. The small self-purge orifice can be seen in this view, lower middle to the right of separator. 3D model Ray Matter

B pump housing - sectioned / polished

B pump housing from pump rotor side – notional surface polish to show shape and detail (such a surface was not used on the actual pump parts). The casing has been cut to show the internal rotor space detail. The outlet throat, right, and spiral volute space are displayed in this view as is the central fuel inlet. 3D model Ray Matter

Over-speed trip switch: exposed

Over-speed trip switch: exposed

Detail of fuel pump face plate showing over-speed switch and mounting. The eccentric centrifugal rotor can be seen (brass coloured part). This unbalanced part rotates against a spring load that allows the thicker (proportionally heavier) section of the rotor to move outwards from the center as the rotational speed rises and push the release rod clear of a keyed section of the plunger shaft (part with disc shaped knob on left) thus operating a relay switch that shuts down the flow of steam to the turbine. 3D model Ray Matter
