Flow Rate: The flow rate of a hydraulic gear pump is typically measured in gallons per minute (GPM) or liters per minute (LPM).
It indicates how much hydraulic fluid the pump can deliver in a given time. The specific flow rate would depend on the model and size of the pump.
Operating Pressure: Hydraulic systems operate under specific pressure requirements. The pump should be capable of providing the required pressure, usually measured in pounds per square inch (psi) or bars. Common hydraulic systems may operate at pressures ranging from hundreds to thousands of psi.
Displacement: The displacement of a hydraulic gear pump is a measure of the volume of fluid it can transfer per revolution of the gears. It's typically expressed in cubic inches per revolution (in³/rev) or cubic centimeters per revolution (cc/rev). Displacement determines the pump's capacity to move fluid and is closely related to the flow rate.
Material and Construction: Hydraulic gear pumps are often made from materials like cast iron, aluminum, or steel. The choice of material depends on factors such as the operating environment, fluid compatibility, and intended application. The construction should be durable and able to withstand the demands of the hydraulic system.
Inlet and Outlet Ports: Hydraulic gear pumps have specific inlet and outlet ports where hydraulic fluid is connected.
The size and type of these ports may vary depending on the pump's design and intended application.
Speed Range: Some hydraulic gear pumps are designed for specific speed ranges, so it's essential to match the pump's speed capabilities with the requirements of your hydraulic system.
Efficiency: The efficiency of a hydraulic gear pump can affect the overall energy consumption and performance of a hydraulic system. Higher efficiency pumps waste less energy as heat and are generally preferred.
Mounting Options: Hydraulic gear pumps come in various configurations for different mounting options, such as flange-mounted, foot-mounted, or even close-coupled configurations. The choice of mounting can impact the pump's integration into your system.
