The “100” in the model number 90R100 indicates a nominal displacement of 100 cubic centimeters per revolution (cm³/rev). As a variable or fixed displacement pump (depending on the specific design denoted by the additional codes), this displacement value determines the volume of hydraulic fluid the pump can move in one revolution, which in turn affects its flow rate and power output capabilities.
Operating Pressure
Rated Pressure: The rated pressure of these 90R100 pumps is typically around 350 bar (35 MPa). This pressure rating allows the pump to effectively drive hydraulic actuators in various systems, providing the necessary force for functions such as lifting, moving, and positioning components in machinery.
Maximum Pressure: The maximum pressure that the pumps can withstand for short periods is usually higher than the rated pressure, reaching up to 420 bar (42 MPa) or more. This extra pressure capacity enables the pumps to handle sudden high-load situations that may occur during operation, ensuring the system's reliability under demanding conditions.
