Flow Rate: One of the most critical specifications for a hydraulic gear pump is its flow rate, usually measured in gallons per minute (GPM) or liters per minute (LPM).

The flow rate represents the volume of hydraulic fluid the pump can deliver in a specific time frame.

Pressure Rating: Hydraulic gear pumps have a maximum pressure rating, often measured in pounds per square inch (PSI) or bars. This rating indicates the maximum pressure the pump can handle safely while delivering fluid.

Displacement: The displacement of a gear pump refers to the volume of fluid displaced per revolution of the pump's gears. It is typically expressed in cubic inches or cubic centimeters per revolution.

Construction Material: Gear pumps are commonly made from materials like cast iron, aluminum, or alloy steel. The choice of material affects the pump's durability, resistance to corrosion, and suitability for specific applications.

Mounting Configuration: Gear pumps can have various mounting configurations, including flange mount, direct mount, and SAE mount. The choice of mounting configuration depends on the equipment and system's design.

Shaft Design: The pump's shaft design may vary, with options like splined, keyed, or threaded shafts, which connect to the power source (e.g., engine) to transfer rotational energy to the pump.

Seal Type: Hydraulic gear pumps are equipped with seals and gaskets to prevent leakage and maintain system integrity.

The type of seals used can influence the pump's compatibility with different hydraulic fluids and operating conditions.

Operating Speed: The operating speed of a gear pump is measured in revolutions per minute (RPM) and is crucial for determining its performance and efficiency.

Temperature Range: Gear pumps should operate within specific temperature ranges to ensure optimal performance. Manufacturers provide temperature limits to guide users in choosing the right pump for their applications.

Viscosity Range: The viscosity of the hydraulic fluid being used is essential, as it affects the pump's efficiency and performance. Gear pumps typically have a recommended viscosity range.
