Displacement: Usually measured in cubic centimeters per revolution (cm³/rev). For example, the "0800" in the model numbers might indicate a displacement of 800 cm³/rev. This parameter determines the volume of fluid the pump can deliver per rotation.
Rated Pressure: The maximum pressure at which the pump is designed to operate continuously under normal conditions. It could be, for instance, 35 MPa (megapascals) for high – pressure applications in injection molding machines.
Maximum Pressure: The highest pressure that the pump can briefly withstand without suffering damage. It is typically higher than the rated pressure, perhaps 40 – 45 MPa. This is important for handling peak pressure demands during the injection molding process.
Rated Speed: The recommended rotational speed at which the pump should operate to achieve optimal performance. It might be 1500 – 2000 rpm (revolutions per minute), depending on the specific design and motor characteristics. Operating at the rated speed ensures efficient fluid delivery and proper functioning of the servo – control system.
Flow Rate: The volume of fluid that the pump can deliver per unit of time. At the rated speed and pressure, the flow rate could be, say, 120 – 150 liters per minute (L/min), which is crucial for meeting the injection molding machine's fluid – supply requirements.
