  • Using a load sense pump as a backup for a pressure-compensated pump
    Patent number: 11448240
    Abstract: A load sense pump can be used as a backup for a pressure-compensated pump in a wellbore operation. A pumping system can include a first pump, a second pump, a check valve, and a directional control valve. The first pump, which can be a load sense pump, can be used to provide pressure to a first hydraulic load. The second pump, which can be a pressure-compensated pump, can be used to provide pressure to a second hydraulic load. The directional control valve can be controllable to cause the first pump to change operation to provide pressure to the first hydraulic load and through the check valve to the second hydraulic load.
