A fluid pumping system comprising: a pump to provide fluid to an actuator that is operated by the fluid, the pump including, a first fluid driver including, a first prime mover, the first prime mover being at least one of a variable-speed and a variable-torque prime mover, and a first fluid displacement member to be driven by the first prime mover; a second fluid driver including, a second prime mover, the second prime mover being at least one of a variable-speed and a variable-torque prime mover, and a second fluid displacement member to be driven by the second prime mover, the first fluid displacement member and the second fluid displacement member being disposed so as to transfer fluid from an inlet port (22, 24) of the pump to an outlet port (22, 24) of the pump; a proportional control valve assembly including, a proportional control valve disposed in the fluid pumping system such that the proportional control valve is in fluid communication with the pump, and a valve actuator to operate the proportional control valve; and a controller having a fluid control module for controlling fluid-related functions in the system, the controller communicating with a pump control circuit to establish at least one of a speed and a torque of the first and second prime movers (41,61) to adjust at least one of a flow in the system to a flow set point and a pressure in the system to a pressure set point, and communicating with a valve control circuit to concurrently establish an opening of the proportional control valve to adjust at least one of the flow to the flow set point and the pressure to the pressure set point, characterised in that the controller establishes a first position of at least one of a first protrusion and indent on the first fluid displacement member relative to a second position of at least one of a second protrusion and indent on the second fluid displacement member so as to create synchronized contact between the first fluid displacement member and the second fluid displacement member to seal a fluid path from the outlet of the pump to the inlet (22,24) of the pump. a pump to provide fluid to an actuator that is operated by the fluid, the pump including, a first fluid driver including, a first prime mover, the first prime mover being at least one of a variable-speed and a variable-torque prime mover, and a first fluid displacement member to be driven by the first prime mover; a second fluid driver including, a second prime mover, the second prime mover being at least one of a variable-speed and a variable-torque prime mover, and a second fluid displacement member to be driven by the second prime mover, the first fluid displacement member and the second fluid displacement member being disposed so as to transfer fluid from an inlet port (22, 24) of the pump to an outlet port (22, 24) of the pump; a first fluid driver including, a first prime mover, the first prime mover being at least one of a variable-speed and a variable-torque prime mover, and a first fluid displacement member to be driven by the first prime mover; a second fluid driver including, a second prime mover, the second prime mover being at least one of a variable-speed and a variable-torque prime mover, and a second fluid displacement member to be driven by the second prime mover, the first fluid displacement member and the second fluid displacement member being disposed so as to transfer fluid from an inlet port (22, 24) of the pump to an outlet port (22, 24) of the pump; a proportional control valve assembly including, a proportional control valve disposed in the fluid pumping system such that the proportional control valve is in fluid communication with the pump, and a valve actuator to operate the proportional control valve; and a controller having a fluid control module for controlling fluid-related functions in the system, the controller communicating with a pump control circuit to establish at least one of a speed and a torque of the first and second prime movers (41,61) to adjust at least one of a flow in the system to a flow set point and a pressure in the system to a pressure set point, and communicating with a valve control circuit to concurrently establish an opening of the proportional control valve to adjust at least one of the flow to the flow set point and the pressure to the pressure set point, characterised in that the controller establishes a first position of at least one of a first protrusion and indent on the first fluid displacement member relative to a second position of at least one of a second protrusion and indent on the second fluid displacement member so as to create synchronized contact between the first fluid displacement member and the second fluid displacement member to seal a fluid path from the outlet of the pump to the inlet (22,24) of the pump.
