Hot sale 5B1 1518222228 HYDRAULIC GEAR PUMP | Partsdic®

A hydraulic gear pump operates based on the principle of positive displacement.

It consists of two meshing gears, typically made of high-strength materials like steel or cast iron. As the gears rotate, they trap and displace hydraulic fluid, creating a continuous flow and building pressure within the system.

Flow Rate and Pressure:
Hydraulic gear pumps are available in various sizes and configurations, allowing for a wide range of flow rates and pressure capabilities. These pumps can handle pressures typically ranging from 1000 to 5000 psi (pounds per square inch) and can deliver flow rates from a few gallons per minute (GPM) to over 100 GPM, depending on the model and application requirements.

There are two primary designs of hydraulic gear pumps: external gear pumps and internal gear pumps.

External Gear Pump: In this design, the two gears are external to the pump housing and mesh externally. They are commonly used for medium-pressure applications and are known for their simplicity and reliability.

Internal Gear Pump: Internal gear pumps have one gear inside another. These pumps are often used for high-pressure applications and offer a more compact design.

Efficiency and Noise Levels:
Hydraulic gear pumps are known for their high volumetric efficiency, which means they can maintain a consistent flow rate with minimal leakage.

However, they can be relatively noisy compared to other pump types, which may require additional noise reduction measures in some applications.

Fluid Compatibility:
Hydraulic gear pumps are compatible with a wide range of hydraulic fluids, including mineral-based oils, synthetic oils, and some biodegradable fluids. Proper fluid selection is essential to ensure optimal pump performance and longevity.

Mounting Options:
These pumps come with various mounting options, making them adaptable to different installation requirements. Common mounting configurations include flange mount, foot mount, and direct drive.

Temperature and Viscosity Range:
Hydraulic gear pumps are designed to operate within specific temperature and viscosity ranges. It's important to choose a pump that suits the environmental conditions and fluid properties of the application.
