An operational control device is disclosed for a positive-displacement pump having a motor, means for actuating the motor, state sensor means for detecting an actual operating parameter (e.g., pressure) of the pump, and operating mode means for controlling an operating mode of the pump. A first actuating mode of the operating mode means is set by the actuating means below a first operating-parameter threshold value (P1). This mode brings about a constantly rising pump pressure in the direction of an operating-parameter setpoint value (Pset) in a variable manner, which is dependent on a detected change in the operating parameter over a predefined time interval. A second actuating mode is set as normal operation to the operating-parameter setpoint value by the actuating means above the first operating-parameter threshold value. P1 is fixed or is calculated as a fraction of the operating-parameter setpoint value and/or a pump parameter correlated therewith.

A gear pump includes: a first pump constructed from a first drive gear rotated by driving of a drive shaft and a first driven gear rotatably arranged coaxially with a rotary shaft; and a second pump constructed from a second drive gear rotatably provided coaxially with the rotary shaft and a second driven gear. The rotary shaft allows the first driven gear and the second drive gear to engage with and disengage from each other in a rotation direction by movement to an axial direction. When the discharge pressure is higher than predetermined pressure, rotation of the first driven gear is not transmitted to the second drive gear and only the first pump operates. When the discharge pressure becomes the predetermined pressure or less, the rotation of the first driven gear is transmitted to the second drive gear and the first and the second pumps operate.
