Phil,
The speed is controlled by the fuel going to the burners, N1 in my book, this is determined by the demands of the throttles set by the crew. This is basic gas turbine operation.

I meant the speed of operation of the fuel pump.
The fuel valves were open, the throttles (and auto-pilot) demanded an engine speed higher than that acheived, the actual speed of the fuel pumps doesn't seem to have been stated in the special report.
