Work order: Calculating a gear pump

A cylinder (4000/150/50) should extend at a speed of 0.02 m/s. Your work order is to select the right pump from the manual, which can deliver the necessary volume flow. The longer the system is in operation, the more the volumetric efficiency of the pump will deteriorate. Furthermore, you do not want to operate the pump at its performance limit. Therefore, multiply a safety factor of 1.2 to your result.

The pump is driven by a three-phase asynchronous motor, whose nominal speed is 1440 /min at 50 Hz mains voltage.
