| The Mover and the Lobe pump are powered by the power pack via
umbilcals from two hose reels mounted on a separate frame in order that
the power pack may be sited away from the tank. The umbilical for the
Mover has an additional service hose for the breathing air supply for
the Mover operator. This is another NES safety feature as the airline
hose is protected inside the sheathed umbilical. The engine is fitted
with many safety features including spark arrestor and Chalwyn air inlet
shut down valve. Both the power pack and hose reels are frame protected
and are equipped with lifting points. The 670 Rotary Lobe pump can
pump up to 162m/3 per hour with a maximum discharge pressure of 6.3 bar.
Fitted to a trolley for ease of movement inside a tank it can be used up
to 100 meters away from the reels via the umbilical. To maximize pumping
efficiency, suction is direct into the pump via the 90 degree elbow.
Discharge is normally through lightweight bauer type piping. Control of
the pump is by the control block mounted on the pump or directly from
the power pack.
