Pump Fixing

If a rotor failure occurs, the connection of the pump to the system could be
WARNING!
subjected to a significant torque. If the connection is not sufficient to
withstand that torque, the pump could detach from the system or the motor
housing could detach from the pump envelope. In this case metal fragments
could be projected from the pump or system, which could cause serious
injury or death and/or damage to surrounding equipment.
Fix the TV 902 Navigator in a stable position, mounting the inlet
flange of the turbopump to the system counter-flange, with a
connection capable of withstanding a torque of 6800 Nm around its
axis.
For example, this Bolted Flange can be fixed using high strength M10
steel screws (class higher than 8.8).
The following table shows the necessary number of screws and the
relevant fixing torque.
