Rated Pressure: The 90R series pumps typically have a rated pressure in the range of 350 bar (35 MPa) to 400 bar (40 MPa). This allows them to handle high - pressure hydraulic systems commonly found in industrial and mobile applications.
Maximum Pressure: The maximum pressure that the pumps can withstand for short periods is usually higher than the rated pressure, reaching up to 450 bar (45 MPa) or more, depending on the specific model and application requirements.
Flow Rate: The flow rate of the pumps is directly proportional to their displacement and rotational speed. At a given speed, the larger the displacement, the higher the flow rate. For example, at a speed of 1500 rpm:
90R42: Flow rate = 42 cm³/rev × 1500 rpm = 63000 cm³/min = 63 L/min.
90R250: Flow rate = 250 cm³/rev × 1500 rpm = 375000 cm³/min = 375 L/min.
