Abstract : A rotary pump system includes a rotary pump, a turbine for driving the pump, and a coupling interconnecting a shaft of the turbine and a shaft of the pump. A speed monitoring system determines rotational speed of the pump shaft, is programmed with selected speeds for the pump during operation, and is adapted to send a signal responsive to a difference between the determined speed and the programmed speed. A brake is engageable with the coupling, and a brake valve is adapted to receive the signal and, in response thereto, to operate the brake to conform the speed of the pump to the programmed speed.
