Abstract
A controllable pump system can include an inlet line and a pressure controlled pump connected to the inlet line to receive input flow. The pressure controlled pump can have a pressure controlled pump state configured to control a pump output to an output line connected to the pressure controlled pump. The system can include a slew pump connected to the inlet line and configured to output a slew pump pressure, and a slew pressure valve connected to the input line and to a second line and configured to output a control pressure to the pressure controlled pump. The second line can be configured to be in fluid communication with at least the slew pump such that the slew pressure valve can receive the slew pump pressure.
