GE FR9E GT Charge Pump

Hi,

I am working in the erection/commissioning team of a gas turbine project involving a GE Fr. 9E gas turbine. In our accessory module we are having a charge pump connected to the input gear and finally the torque converter. During Oil Flushing, the torque converter and hence the starting induction motor was rotating because oil was flowing through the charge pump into the "starting means" circuit. In our site we put a blind on the inlet of the charge pump thereby stopping the rotation. (A creaking sound was coming occasionally) If somebody can tell the function of the charge pump then it will be very useful.
