Operating Principles: Barnes Gear Pumps operate on the principle of positive displacement.
They consist of two interlocking gears, typically helical or spur in design, housed within a pump casing. As these gears rotate, fluid is trapped in the spaces between the gear teeth and carried from the inlet to the outlet, creating a steady flow of fluid.
Materials of Construction: Barnes Gear Pumps are manufactured using a range of materials, including cast iron, aluminum, and stainless steel. The choice of material depends on the specific application and the compatibility of the fluid being pumped.
Flow Rate: These pumps are capable of delivering a wide range of flow rates, making them suitable for both low-flow and high-flow applications. Flow rates typically range from a few liters per minute to several thousand liters per minute.
Pressure Rating: Barnes Gear Pumps can generate high pressure levels, making them suitable for applications where a significant amount of pressure is required to move fluids. Pressure ratings can range from a few bar to several hundred bar, depending on the pump size and design.
Viscosity Handling: One of the strengths of gear pumps is their ability to handle a broad range of fluid viscosities. Barnes Gear Pumps are particularly adept at pumping viscous fluids such as oils, syrups, and molasses. They are also capable of handling thin, low-viscosity liquids.
Temperature Range: These pumps can operate within a wide temperature range, from sub-zero temperatures to high-temperature applications. The specific temperature limits depend on the materials used in the pump construction.
Sealing Options: Barnes Gear Pumps are available with various sealing options, including packing seals, mechanical seals, and lip seals.
The choice of seal type depends on the application requirements and the nature of the fluid being pumped.
Mounting Options: These pumps come in various mounting configurations, including close-coupled, pedestal-mounted, and flange-mounted designs. This versatility allows for easy integration into different systems.
Drive Options: Barnes Gear Pumps can be powered by various drive mechanisms, including electric motors, hydraulic motors, and even hand-cranked options for manual operation. The choice of drive depends on the power source available and the specific application.
Noise and Vibration: Gear pumps are known for their quiet and smooth operation. They produce minimal noise and vibration, making them suitable for applications where noise pollution and vibration are a concern.
Maintenance and Longevity: These pumps are relatively easy to maintain and have a long service life when properly cared for. Routine maintenance typically includes checking and replacing seals and lubricating gear teeth.
