Type of Pump: Confirm whether it is indeed a hydraulic gear pump.
Hydraulic gear pumps use intermeshing gears to pump hydraulic fluid.
Flow Rate: The flow rate, usually measured in liters per minute (LPM) or gallons per minute (GPM), indicates how much hydraulic fluid the pump can deliver per unit of time. Different models may have varying flow rates to suit different applications.
Operating Pressure: Hydraulic gear pumps typically operate within a specified pressure range, usually expressed in pounds per square inch (PSI) or bar. Knowing the operating pressure is crucial to ensure it meets the requirements of your hydraulic system.
Materials: The pump's construction materials are essential for durability and compatibility with various hydraulic fluids. Common materials include cast iron, steel, and some models with aluminum components.
Size and Dimensions: The physical size and dimensions of the pump are essential to ensure it can fit within your hydraulic system's available space and configuration.
Mounting Options: Hydraulic gear pumps often come with different mounting options (e.g., flange or foot-mounted) to accommodate various installation requirements.
Sealing: Information on the type of seals used in the pump to prevent fluid leakage and contamination.
Efficiency: The efficiency of the pump, often expressed as a percentage, indicates how effectively it converts mechanical energy into hydraulic power. Higher efficiency means less wasted energy as heat.
Noise Levels: Some specifications may include noise levels during operation, which can be crucial for applications where noise is a concern.
Temperature Range: The temperature range within which the pump can safely and efficiently operate.
Fluid Compatibility: Ensure that the pump is compatible with the type of hydraulic fluid (e.g., mineral oil, synthetic oil, etc.) you intend to use in your hydraulic system.
Maintenance Requirements: Information on routine maintenance tasks, such as seal replacement or gear inspection, and recommended service intervals.
