The 39857A03 hydraulic gear pump is characterized by its robust and durable design.
It consists of two intermeshing gears within a sealed housing. These gears, typically made of high-strength materials like steel or cast iron, rotate within tight tolerances, creating chambers that vary in size as they mesh and unmesh. This action generates suction and discharge, facilitating the movement of hydraulic fluid through the system.
Flow Rate and Pressure Rating:
One of the primary specifications of this hydraulic gear pump is its flow rate and pressure rating. These pumps are available in various sizes, with flow rates typically ranging from 0.5 to 20 gallons per minute (GPM) or more. Pressure ratings can vary but often fall within the range of 1000 to 3000 pounds per square inch (psi). These variations allow for flexibility in choosing the pump that best suits the specific needs of a hydraulic system.
Efficiency and Reliability:
The 39857A03 pump is known for its efficiency and reliability. Due to the precision engineering of its gears and housing, it minimizes internal leakage, resulting in high volumetric efficiency. This means more hydraulic fluid is moved with less power input, leading to energy savings and reduced heat generation. Additionally, the simple design of gear pumps contributes to their reliability, as they have fewer components prone to wear and tear.
Viscosity Compatibility:
Another crucial specification to consider is the viscosity compatibility of the hydraulic gear pump.
These pumps can handle a wide range of hydraulic fluids, including oil-based fluids with varying viscosities. This versatility makes them suitable for various applications, from low-viscosity fluids used in mobile equipment to high-viscosity fluids in industrial machinery.
Mounting Options:
The 39857A03 pump offers different mounting options, including flange, foot, and bracket mounts, allowing for easy integration into diverse hydraulic systems. The choice of mounting depends on the available space and the specific requirements of the application.
